/// Implements a client for the Cloud Trace API.
///
/// # Example
/// ```
/// # use google_cloud_trace_v2::client::TraceService;
/// # async fn sample() -> Result<(), Box<dyn std::error::Error>> {
///     let client = TraceService::builder().build().await?;
///     client.batch_write_spans()
///         /* set fields */
///         .send().await?;
/// # Ok(()) }
/// ```
///
/// # Service Description
///
/// Service for collecting and viewing traces and spans within a trace.
///
/// A trace is a collection of spans corresponding to a single
/// operation or a set of operations in an application.
///
/// A span is an individual timed event which forms a node of the trace tree.
/// A single trace can contain spans from multiple services.
///
/// # Configuration
///
/// To configure `TraceService` use the `with_*` methods in the type returned
/// by [builder()][TraceService::builder]. The default configuration should
/// work for most applications. Common configuration changes include
///
/// * [with_endpoint()]: by default this client uses the global default endpoint
///   (`https://cloudtrace.googleapis.com`). Applications using regional
///   endpoints or running in restricted networks (e.g. a network configured
//    with [Private Google Access with VPC Service Controls]) may want to
///   override this default.
/// * [with_credentials()]: by default this client uses
///   [Application Default Credentials]. Applications using custom
///   authentication may need to override this default.
///
/// [with_endpoint()]: super::builder::trace_service::ClientBuilder::with_endpoint
/// [with_credentials()]: super::builder::trace_service::ClientBuilder::with_credentials
/// [Private Google Access with VPC Service Controls]: https://cloud.google.com/vpc-service-controls/docs/private-connectivity
/// [Application Default Credentials]: https://cloud.google.com/docs/authentication#adc
///
/// # Pooling and Cloning
///
/// `TraceService` holds a connection pool internally, it is advised to
/// create one and reuse it. You do not need to wrap `TraceService` in
/// an [Rc](std::rc::Rc) or [Arc](std::sync::Arc) to reuse it, because it
/// already uses an `Arc` internally.
