    # @option options [required, Aws::CredentialProvider] :credentials
    #   Your AWS credentials. This can be an instance of any one of the
    #   following classes:
    #
    #   * `Aws::Credentials` - Used for configuring static, non-refreshing
    #     credentials.
    #
    #   * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #     from an EC2 IMDS on an EC2 instance.
    #
    #   * `Aws::SharedCredentials` - Used for loading credentials from a
    #     shared file, such as `~/.aws/config`.
    #
    #   * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #   When `:credentials` are not configured directly, the following
    #   locations will be searched for credentials:
    #
    #   * `Aws.config[:credentials]`
    #   * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #   * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #   * `~/.aws/credentials`
    #   * `~/.aws/config`
    #   * EC2 IMDS instance profile - When used by default, the timeouts are
    #     very aggressive. Construct and pass an instance of
    #     `Aws::InstanceProfileCredentails` to enable retries and extended
    #     timeouts.
    #
    # @option options [required, String] :region
    #   The AWS region to connect to.  The configured `:region` is
    #   used to determine the service `:endpoint`. When not passed,
    #   a default `:region` is search for in the following locations:
    #
    #   * `Aws.config[:region]`
    #   * `ENV['AWS_REGION']`
    #   * `ENV['AMAZON_REGION']`
    #   * `ENV['AWS_DEFAULT_REGION']`

    # @option options [Boolean] :convert_params (true)
    #   When `true`, an attempt is made to coerce request parameters into
    #   the required types.
    #
    # @option options [String] :endpoint
    #   The client endpoint is normally constructed from the `:region`
    #   option. You should only configure an `:endpoint` when connecting
    #   to test endpoints. This should be avalid HTTP(S) URI.
    #
    # @option options [Aws::Log::Formatter] :log_formatter (Aws::Log::Formatter.default)
    #   The log formatter.
    #
    # @option options [Symbol] :log_level (:info)
    #   The log level to send messages to the `:logger` at.
    #
    # @option options [Logger] :logger
    #   The Logger instance to send log messages to.  If this option
    #   is not set, logging will be disabled.
    #
    # @option options [String] :profile ("default")
    #   Used when loading credentials from the shared credentials file
    #   at HOME/.aws/credentials.  When not specified, 'default' is used.
    #
    # @option options [Integer] :retry_limit (3)
    #   The maximum number of times to retry failed requests.  Only
    #   ~ 500 level server errors and certain ~ 400 level client errors
    #   are retried.  Generally, these are throttling errors, data
    #   checksum errors, networking errors, timeout errors and auth
    #   errors from expired credentials.
    #
    # @option options [String] :secret_access_key
    #
    # @option options [String] :session_token
    #
    # @option options [Boolean] :stub_responses (false)
    #   Causes the client to return stubbed responses. By default
    #   fake responses are generated and returned. You can specify
    #   the response data to return or errors to raise by calling
    #   {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #   ** Please note ** When response stubbing is enabled, no HTTP
    #   requests are made, and retries are disabled.

    # @!group API Operations

    # Returns a set of temporary security credentials (consisting of an
    # access key ID, a secret access key, and a security token) that you can
    # use to access AWS resources that you might not normally have access
    # to. Typically, you use `AssumeRole` for cross-account access or
    # federation. For a comparison of `AssumeRole` with the other APIs that
    # produce temporary credentials, see [Requesting Temporary Security
    # Credentials][1] and [Comparing the AWS STS APIs][2] in the *IAM User
    # Guide*.
    #
    # **Important:** You cannot call `AssumeRole` by using AWS root account
    # credentials; access is denied. You must use credentials for an IAM
    # user or an IAM role to call `AssumeRole`.
    #
    # For cross-account access, imagine that you own multiple accounts and
    # need to access resources in each account. You could create long-term
    # credentials in each account to access those resources. However,
    # managing all those credentials and remembering which one can access
    # which account can be time consuming. Instead, you can create one set
    # of long-term credentials in one account and then use temporary
    # security credentials to access all the other accounts by assuming
    # roles in those accounts. For more information about roles, see [IAM
    # Roles (Delegation and Federation)][3] in the *IAM User Guide*.
    #
    # For federation, you can, for example, grant single sign-on access to
    # the AWS Management Console. If you already have an identity and
    # authentication system in your corporate network, you don't have to
    # recreate user identities in AWS in order to grant those user
    # identities access to AWS. Instead, after a user has been
    # authenticated, you call `AssumeRole` (and specify the role with the
    # appropriate permissions) to get temporary security credentials for
    # that user. With those temporary security credentials, you construct a
    # sign-in URL that users can use to access the console. For more
    # information, see [Common Scenarios for Temporary Credentials][4] in
    # the *IAM User Guide*.
    #
    # The temporary security credentials are valid for the duration that you
    # specified when calling `AssumeRole`, which can be from 900 seconds (15
    # minutes) to a maximum of 3600 seconds (1 hour). The default is 1 hour.
    #
    # The temporary security credentials created by `AssumeRole` can be used
    # to make API calls to any AWS service with the following exception: you
    # cannot call the STS service's `GetFederationToken` or
    # `GetSessionToken` APIs.
    #
    # Optionally, you can pass an IAM access policy to this operation. If
    # you choose not to pass a policy, the temporary security credentials
    # that are returned by the operation have the permissions that are
    # defined in the access policy of the role that is being assumed. If you
    # pass a policy to this operation, the temporary security credentials
    # that are returned by the operation have the permissions that are
    # allowed by both the access policy of the role that is being assumed,
    # <i> <b>and</b> </i> the policy that you pass. This gives you a way to
    # further restrict the permissions for the resulting temporary security
    # credentials. You cannot use the passed policy to grant permissions
    # that are in excess of those allowed by the access policy of the role
    # that is being assumed. For more information, see [Permissions for
    # AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity][5] in
    # the *IAM User Guide*.
    #
    # To assume a role, your AWS account must be trusted by the role. The
    # trust relationship is defined in the role's trust policy when the
    # role is created. That trust policy states which accounts are allowed
    # to delegate access to this account's role.
    #
    # The user who wants to access the role must also have permissions
    # delegated from the role's administrator. If the user is in a
    # different account than the role, then the user's administrator must
    # attach a policy that allows the user to call AssumeRole on the ARN of
    # the role in the other account. If the user is in the same account as
    # the role, then you can either attach a policy to the user (identical
    # to the previous different account user), or you can add the user as a
    # principal directly in the role's trust policy
    #
    # **Using MFA with AssumeRole**
    #
    # You can optionally include multi-factor authentication (MFA)
    # information when you call `AssumeRole`. This is useful for
    # cross-account scenarios in which you want to make sure that the user
    # who is assuming the role has been authenticated using an AWS MFA
    # device. In that scenario, the trust policy of the role being assumed
    # includes a condition that tests for MFA authentication; if the caller
    # does not include valid MFA information, the request to assume the role
    # is denied. The condition in a trust policy that tests for MFA
    # authentication might look like the following example.
    #
    # `"Condition": \{"Bool": \{"aws:MultiFactorAuthPresent": true\}\}`
    #
    # For more information, see [Configuring MFA-Protected API Access][6] in
    # the *IAM User Guide* guide.
    #
    # To use MFA with `AssumeRole`, you pass values for the `SerialNumber`
    # and `TokenCode` parameters. The `SerialNumber` value identifies the
    # user's hardware or virtual MFA device. The `TokenCode` is the
    # time-based one-time password (TOTP) that the MFA devices produces.

    # @option params [required, String] :role_arn
    #   The Amazon Resource Name (ARN) of the role to assume.
    #
    # @option params [required, String] :role_session_name
    #   An identifier for the assumed role session.
    #
    #   Use the role session name to uniquely identify a session when the same
    #   role is assumed by different principals or for different reasons. In
    #   cross-account scenarios, the role session name is visible to, and can
    #   be logged by the account that owns the role. The role session name is
    #   also used in the ARN of the assumed role principal. This means that
    #   subsequent cross-account API requests using the temporary security
    #   credentials will expose the role session name to the external account
    #   in their CloudTrail logs.
    #
    #   The regex used to validate this parameter is a string of characters
    #   consisting of upper- and lower-case alphanumeric characters with no
    #   spaces. You can also include underscores or any of the following
    #   characters: =,.@-
    #
    # @option params [String] :policy
    #   An IAM policy in JSON format.
    #
    #   This parameter is optional. If you pass a policy, the temporary
    #   security credentials that are returned by the operation have the
    #   permissions that are allowed by both (the intersection of) the access
    #   policy of the role that is being assumed, *and* the policy that you
    #   pass. This gives you a way to further restrict the permissions for the
    #   resulting temporary security credentials. You cannot use the passed
    #   policy to grant permissions that are in excess of those allowed by the
    #   access policy of the role that is being assumed. For more information,
    #   see [Permissions for AssumeRole, AssumeRoleWithSAML, and
    #   AssumeRoleWithWebIdentity][1] in the *IAM User Guide*.
    #
    #   The format for this parameter, as described by its regex pattern, is a
    #   string of characters up to 2048 characters in length. The characters
    #   can be any ASCII character from the space character to the end of the
    #   valid character list (\\u0020-\\u00FF). It can also include the tab
    #   (\\u0009), linefeed (\\u000A), and carriage return (\\u000D)
    #   characters.
    #
    #   <note markdown="1"> The policy plain text must be 2048 bytes or shorter. However, an
    #   internal conversion compresses it into a packed binary format with a
    #   separate limit. The PackedPolicySize response element indicates by
    #   percentage how close to the upper size limit the policy is, with 100%
    #   equaling the maximum allowed size.

    # @option params [Integer] :duration_seconds
    #   The duration, in seconds, of the role session. The value can range
    #   from 900 seconds (15 minutes) to 3600 seconds (1 hour). By default,
    #   the value is set to 3600 seconds.
    #
    #   <note markdown="1"> This is separate from the duration of a console session that you might
    #   request using the returned credentials. The request to the federation
    #   endpoint for a console sign-in token takes a `SessionDuration`
    #   parameter that specifies the maximum length of the console session,
    #   separately from the `DurationSeconds` parameter on this API. For more

    # @option params [String] :external_id
    #   A unique identifier that is used by third parties when assuming roles
    #   in their customers' accounts. For each role that the third party can
    #   assume, they should instruct their customers to ensure the role's
    #   trust policy checks for the external ID that the third party
    #   generated. Each time the third party assumes the role, they should
    #   pass the customer's external ID. The external ID is useful in order
    #   to help third parties bind a role to the customer who created it. For
    #   more information about the external ID, see [How to Use an External ID

    #
    # @option params [String] :serial_number
    #   The identification number of the MFA device that is associated with
    #   the user who is making the `AssumeRole` call. Specify this value if
    #   the trust policy of the role being assumed includes a condition that
    #   requires MFA authentication. The value is either the serial number for
    #   a hardware device (such as `GAHT12345678`) or an Amazon Resource Name
    #   (ARN) for a virtual device (such as
    #   `arn:aws:iam::123456789012:mfa/user`).
    #
    #   The regex used to validate this parameter is a string of characters

    #
    # @option params [String] :token_code
    #   The value provided by the MFA device, if the trust policy of the role
    #   being assumed requires MFA (that is, if the policy includes a
    #   condition that tests for MFA). If the role being assumed requires MFA
    #   and if the `TokenCode` value is missing or expired, the `AssumeRole`
    #   call returns an "access denied" error.
    #

    # Before your application can call `AssumeRoleWithSAML`, you must
    # configure your SAML identity provider (IdP) to issue the claims
    # required by AWS. Additionally, you must use AWS Identity and Access
    # Management (IAM) to create a SAML provider entity in your AWS account
    # that represents your identity provider, and create an IAM role that
    # specifies this SAML provider in its trust policy.
    #
    # Calling `AssumeRoleWithSAML` does not require the use of AWS security
    # credentials. The identity of the caller is validated by using keys in
    # the metadata document that is uploaded for the SAML provider entity
    # for your identity provider.
    #
    # Calling `AssumeRoleWithSAML` can result in an entry in your AWS
    # CloudTrail logs. The entry includes the value in the `NameID` element
    # of the SAML assertion. We recommend that you use a NameIDType that is
    # not associated with any personally identifiable information (PII). For
    # example, you could instead use the Persistent Identifier
    # (`urn:oasis:names:tc:SAML:2.0:nameid-format:persistent`).

    #
    # Calling `AssumeRoleWithWebIdentity` does not require the use of AWS
    # security credentials. Therefore, you can distribute an application
    # (for example, on mobile devices) that requests temporary security
    # credentials without including long-term AWS credentials in the
    # application, and without deploying server-based proxy services that
    # use long-term AWS credentials. Instead, the identity of the caller is
    # validated by using a token from the web identity provider. For a
    # comparison of `AssumeRoleWithWebIdentity` with the other APIs that
    # produce temporary credentials, see [Requesting Temporary Security
    # Credentials][5] and [Comparing the AWS STS APIs][6] in the *IAM User
    # Guide*.
    #
    # The temporary security credentials returned by this API consist of an
    # access key ID, a secret access key, and a security token. Applications
    # can use these temporary security credentials to sign calls to AWS
    # service APIs.
    #
    # The credentials are valid for the duration that you specified when
    # calling `AssumeRoleWithWebIdentity`, which can be from 900 seconds (15
    # minutes) to a maximum of 3600 seconds (1 hour). The default is 1 hour.
    #
    # The temporary security credentials created by
    # `AssumeRoleWithWebIdentity` can be used to make API calls to any AWS
    # service with the following exception: you cannot call the STS
    # service's `GetFederationToken` or `GetSessionToken` APIs.
    #
    # Optionally, you can pass an IAM access policy to this operation. If
    # you choose not to pass a policy, the temporary security credentials
    # that are returned by the operation have the permissions that are
    # defined in the access policy of the role that is being assumed. If you
    # pass a policy to this operation, the temporary security credentials
    # that are returned by the operation have the permissions that are
    # allowed by both the access policy of the role that is being assumed,
    # <i> <b>and</b> </i> the policy that you pass. This gives you a way to
    # further restrict the permissions for the resulting temporary security

    # AssumeRole, AssumeRoleWithSAML, and AssumeRoleWithWebIdentity][7] in
    # the *IAM User Guide*.
    #
    # Before your application can call `AssumeRoleWithWebIdentity`, you must
    # have an identity token from a supported identity provider and create a
    # role that the application can assume. The role that your application
    # assumes must trust the identity provider that is associated with the
    # identity token. In other words, the identity provider must be
    # specified in the role's trust policy.
    #
    # Calling `AssumeRoleWithWebIdentity` can result in an entry in your AWS
    # CloudTrail logs. The entry includes the [Subject][8] of the provided
    # Web Identity Token. We recommend that you avoid using any personally
    # identifiable information (PII) in this field. For example, you could
    # instead use a GUID or a pairwise identifier, as [suggested in the OIDC
    # specification][9].

    # returns an encoded message in addition to returning an HTTP code.
    #
    #  </note>
    #
    # The message is encoded because the details of the authorization status

    #
    # * Whether the request was denied due to an explicit deny or due to the

    # Returns a set of temporary security credentials (consisting of an

    # federated user. A typical use is in a proxy application that gets
    # temporary security credentials on behalf of distributed applications
    # inside a corporate network. Because you must call the
    # `GetFederationToken` action using the long-term security credentials
    # of an IAM user, this call is appropriate in contexts where those
    # credentials can be safely stored, usually in a server-based
    # application. For a comparison of `GetFederationToken` with the other
    # APIs that produce temporary credentials, see [Requesting Temporary
    # Security Credentials][1] and [Comparing the AWS STS APIs][2] in the
    # *IAM User Guide*.
    #
    # <note markdown="1"> If you are creating a mobile-based or browser-based app that can
    # authenticate users using a web identity provider like Login with
    # Amazon, Facebook, Google, or an OpenID Connect-compatible identity
    # provider, we recommend that you use [Amazon Cognito][3] or
    # `AssumeRoleWithWebIdentity`. For more information, see [Federation
    # Through a Web-based Identity Provider][4].
    #
    #  </note>
    #
    # The `GetFederationToken` action must be called by using the long-term
    # AWS security credentials of an IAM user. You can also call
    # `GetFederationToken` using the security credentials of an AWS root
    # account, but we do not recommended it. Instead, we recommend that you
    # create an IAM user for the purpose of the proxy application and then
    # attach a policy to the IAM user that limits federated users to only
    # the actions and resources that they need access to. For more
    # information, see [IAM Best Practices][5] in the *IAM User Guide*.
    #
    # The temporary security credentials that are obtained by using the
    # long-term credentials of an IAM user are valid for the specified
    # duration, from 900 seconds (15 minutes) up to a maximium of 129600
    # seconds (36 hours). The default is 43200 seconds (12 hours). Temporary
    # credentials that are obtained by using AWS root account credentials
    # have a maximum duration of 3600 seconds (1 hour).
    #
    # The temporary security credentials created by `GetFederationToken` can
    # be used to make API calls to any AWS service with the following
    # exceptions:
    #
    # * You cannot use these credentials to call any IAM APIs.
    #
    # * You cannot call any STS APIs except `GetCallerIdentity`.
    #
    # **Permissions**
    #
    # The permissions for the temporary security credentials returned by
    # `GetFederationToken` are determined by a combination of the following:
    #
    # * The policy or policies that are attached to the IAM user whose
    #   credentials are used to call `GetFederationToken`.
    #
    # * The policy that is passed as a parameter in the call.
    #
    # The passed policy is attached to the temporary security credentials
    # that result from the `GetFederationToken` API call--that is, to the
    # *federated user*. When the federated user makes an AWS request, AWS
    # evaluates the policy attached to the federated user in combination
    # with the policy or policies attached to the IAM user whose credentials
    # were used to call `GetFederationToken`. AWS allows the federated
    # user's request only when both the federated user <i> <b>and</b> </i>
    # the IAM user are explicitly allowed to perform the requested action.
    # The passed policy cannot grant more permissions than those that are
    # defined in the IAM user policy.
    #
    # A typical use case is that the permissions of the IAM user whose
    # credentials are used to call `GetFederationToken` are designed to
    # allow access to all the actions and resources that any federated user
    # will need. Then, for individual users, you pass a policy to the
    # operation that scopes down the permissions to a level that's
    # appropriate to that individual user, using a policy that allows only a
    # subset of permissions that are granted to the IAM user.
    #
    # If you do not pass a policy, the resulting temporary security
    # credentials have no effective permissions. The only exception is when
    # the temporary security credentials are used to access a resource that
    # has a resource-based policy that specifically allows the federated
    # user to access the resource.
    #
    # For more information about how permissions work, see [Permissions for
    # GetFederationToken][6]. For information about using
    # `GetFederationToken` to create temporary security credentials, see

    #
    # @option params [String] :policy
    #   An IAM policy in JSON format that is passed with the
    #   `GetFederationToken` call and evaluated along with the policy or
    #   policies that are attached to the IAM user whose credentials are used
    #   to call `GetFederationToken`. The passed policy is used to scope down
    #   the permissions that are available to the IAM user, by allowing only a
    #   subset of the permissions that are granted to the IAM user. The passed
    #   policy cannot grant more permissions than those granted to the IAM
    #   user. The final permissions for the federated user are the most
    #   restrictive set based on the intersection of the passed policy and the
    #   IAM user policy.
    #
    #   If you do not pass a policy, the resulting temporary security
    #   credentials have no effective permissions. The only exception is when
    #   the temporary security credentials are used to access a resource that
    #   has a resource-based policy that specifically allows the federated
    #   user to access the resource.
    #
    #   The format for this parameter, as described by its regex pattern, is a
    #   string of characters up to 2048 characters in length. The characters
    #   can be any ASCII character from the space character to the end of the
    #   valid character list (\\u0020-\\u00FF). It can also include the tab
    #   (\\u0009), linefeed (\\u000A), and carriage return (\\u000D)
    #   characters.
    #
    #   <note markdown="1"> The policy plain text must be 2048 bytes or shorter. However, an
    #   internal conversion compresses it into a packed binary format with a

    # Returns a set of temporary credentials for an AWS account or IAM user.
    # The credentials consist of an access key ID, a secret access key, and
    # a security token. Typically, you use `GetSessionToken` if you want to
    # use MFA to protect programmatic calls to specific AWS APIs like Amazon
    # EC2 `StopInstances`. MFA-enabled IAM users would need to call
    # `GetSessionToken` and submit an MFA code that is associated with their
    # MFA device. Using the temporary security credentials that are returned
    # from the call, IAM users can then make programmatic calls to APIs that
    # require MFA authentication. If you do not supply a correct MFA code,
    # then the API returns an access denied error. For a comparison of

    #
    # The temporary security credentials created by `GetSessionToken` can be

    #
    # * You cannot call any STS API *except* `AssumeRole` or

    #
    # <note markdown="1"> We recommend that you do not call `GetSessionToken` with root account

    #
    #  </note>
    #
    # The permissions associated with the temporary security credentials
