# Client for the TraceService service.
#
# This file describes an API for collecting and viewing traces and spans
# within a trace. A Trace is a collection of spans corresponding to a single
# operation or set of operations for an application. A span is an individual
# timed event which forms a node of the trace tree. A single trace may
# contain span(s) from multiple services.

# config.timeout = 10.0

#
# @yield [config] Configure the Client client.

#
# To create a new TraceService client with a custom
# configuration:

#
# @param name [::String]
# Required. The resource name of the span in the following format:
#
# projects/[PROJECT_ID]/traces/[TRACE_ID]/spans/[SPAN_ID]
#
# [TRACE_ID] is a unique identifier for a trace within a project;
# it is a 32-character hexadecimal encoding of a 16-byte array.
#
# [SPAN_ID] is a unique identifier for a span within a trace; it
# is a 16-character hexadecimal encoding of an 8-byte array.
# @param span_id [::String]
# Required. The [SPAN_ID] portion of the span's resource name.
# @param parent_span_id [::String]
# The [SPAN_ID] of this span's parent span. If this is a root span,
# then this field must be empty.
# @param display_name [::Google::Cloud::Trace::V2::TruncatableString, ::Hash]
# Required. A description of the span's operation (up to 128 bytes).
# Stackdriver Trace displays the description in the
# Google Cloud Platform Console.
# For example, the display name can be a qualified method name or a file name
# and a line number where the operation is called. A best practice is to use
# the same display name within an application and at the same call point.
# This makes it easier to correlate spans in different traces.
# @param start_time [::Google::Protobuf::Timestamp, ::Hash]
# Required. The start time of the span. On the client side, this is the time kept by
# the local machine where the span execution starts. On the server side, this
# is the time when the server's application handler starts running.
# @param end_time [::Google::Protobuf::Timestamp, ::Hash]
# Required. The end time of the span. On the client side, this is the time kept by
# the local machine where the span execution ends. On the server side, this
# is the time when the server application handler stops running.

# A set of attributes on the span. You can have up to 32 attributes per
# span.
# @param stack_trace [::Google::Cloud::Trace::V2::StackTrace, ::Hash]
# Stack trace captured at the start of the span.
# @param time_events [::Google::Cloud::Trace::V2::Span::TimeEvents, ::Hash]
# A set of time events. You can have up to 32 annotations and 128 message
# events per span.
# @param links [::Google::Cloud::Trace::V2::Span::Links, ::Hash]
# Links associated with the span. You can have up to 128 links per Span.
# @param status [::Google::Rpc::Status, ::Hash]
# Optional. The final status for this span.
# @param same_process_as_parent_span [::Google::Protobuf::BoolValue, ::Hash]
# Optional. Set this parameter to indicate whether this span is in
# the same process as its parent. If you do not set this parameter,
# Stackdriver Trace is unable to take advantage of this helpful
# information.
# @param child_span_count [::Google::Protobuf::Int32Value, ::Hash]
# Optional. The number of child spans that were generated while this span
# was active. If set, allows implementation to detect missing child spans.
# @param span_kind [::Google::Cloud::Trace::V2::Span::SpanKind]
# Optional. Distinguishes between spans generated in a particular context. For example,
# two spans with the same name may be distinguished using `CLIENT` (caller)
# and `SERVER` (callee) to identify an RPC call.

# Configuration class for the TraceService API.
#
# This class represents the configuration for TraceService,
# providing control over timeouts, retry behavior, logging, transport
# parameters, and other low-level controls. Certain parameters can also be
# applied individually to specific RPCs. See
# {::Google::Cloud::Trace::V2::TraceService::Client::Configuration::Rpcs}
# for a list of RPCs that can be configured independently.
#
# Configuration can be applied globally to all clients, or to a single client
# on construction.
#
# # Examples
#
# To modify the global config, setting the timeout for batch_write_spans
# to 20 seconds, and all remaining timeouts to 10 seconds:
#
# ::Google::Cloud::Trace::V2::TraceService::Client.configure do |config|
# config.timeout = 10.0
# config.rpcs.batch_write_spans.timeout = 20.0
# end
#
# To apply the above configuration only to a new client:
#
# client = ::Google::Cloud::Trace::V2::TraceService::Client.new do |config|
# config.timeout = 10.0
# config.rpcs.batch_write_spans.timeout = 20.0
# end
