    # @deprecated Use [Aws::S3::Client] #wait_until instead
    #
    # Waiter polls an API operation until a resource enters a desired
    # state.
    #
    # @note The waiting operation is performed on a copy. The original resource
    #   remains unchanged.
    #
    # ## Basic Usage
    #
    # Waiter will polls until it is successful, it fails by
    # entering a terminal state, or until a maximum number of attempts
    # are made.
    #
    #     # polls in a loop until condition is true
    #     resource.wait_until(options) {|resource| condition}
    #
    # ## Example
    #
    #     instance.wait_until(max_attempts:10, delay:5) do |instance|
    #       instance.state.name == 'running'
    #     end
    #
    # ## Configuration
    #
    # You can configure the maximum number of polling attempts, and the
    # delay (in seconds) between each polling attempt. The waiting condition is
    # set by passing a block to {#wait_until}:
    #
    #     # poll for ~25 seconds
    #     resource.wait_until(max_attempts:5,delay:5) {|resource|...}
    #
    # ## Callbacks
    #
    # You can be notified before each polling attempt and before each
    # delay. If you throw `:success` or `:failure` from these callbacks,
    # it will terminate the waiter.
    #
    #     started_at = Time.now
    #     # poll for 1 hour, instead of a number of attempts
    #     proc = Proc.new do |attempts, response|
    #       throw :failure if Time.now - started_at > 3600
    #     end
    #
    #       # disable max attempts
    #     instance.wait_until(before_wait:proc, max_attempts:nil) {...}
    #
    # ## Handling Errors
    #
    # When a waiter is successful, it returns the Resource. When a waiter
    # fails, it raises an error.
    #
    #     begin
    #       resource.wait_until(...)
    #     rescue Aws::Waiters::Errors::WaiterFailed
    #       # resource did not enter the desired state in time
    #     end
    #

    #

    #   terminates because the waiter has entered a state that it will not
    #   transition out of, preventing success.

    #   yet successful.
    #

    #   encountered while polling for a resource that is not expected.

    # @option options [String] :checksum_algorithm
    #   Indicates the algorithm used to create the checksum for the object
    #   when you use the SDK. This header will not provide any additional
    #   functionality if you don't use the SDK. When you send this header,
    #   there must be a corresponding `x-amz-checksum-algorithm ` or
    #   `x-amz-trailer` header sent. Otherwise, Amazon S3 fails the request
    #   with the HTTP status code `400 Bad Request`.
    #
    #   For the `x-amz-checksum-algorithm ` header, replace ` algorithm ` with
    #   the supported algorithm from the following list:
    #
    #   * CRC32
    #
    #   * CRC32C
    #
    #   * SHA1
    #
    #   * SHA256
    #
    #   For more information, see [Checking object integrity][1] in the
    #   *Amazon S3 User Guide*.
    #
    #   If the individual checksum value you provide through
    #   `x-amz-checksum-algorithm ` doesn't match the checksum algorithm you
    #   set through `x-amz-sdk-checksum-algorithm`, Amazon S3 ignores any
    #   provided `ChecksumAlgorithm` parameter and uses the checksum algorithm
    #   that matches the provided value in `x-amz-checksum-algorithm `.
    #
    #   <note markdown="1"> For directory buckets, when you use Amazon Web Services SDKs, `CRC32`
    #   is the default checksum algorithm that's used for performance.
