/// Implements a client for the Cloud Natural Language API.
///
/// # Example
/// ```
/// # use google_cloud_language_v2::client::LanguageService;
/// async fn sample(
/// ) -> anyhow::Result<()> {
///     let client = LanguageService::builder().build().await?;
///     let response = client.analyze_sentiment()
///         /* set fields */
///         .send().await?;
///     println!("response {:?}", response);
///     Ok(())
/// }
/// ```
///
/// # Service Description
///
/// Provides text analysis operations such as sentiment analysis and entity
/// recognition.
///
/// # Configuration
///
/// To configure `LanguageService` use the `with_*` methods in the type returned
/// by [builder()][LanguageService::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://language.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::language_service::ClientBuilder::with_endpoint
/// [with_credentials()]: super::builder::language_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
///
/// `LanguageService` holds a connection pool internally, it is advised to
/// create one and reuse it. You do not need to wrap `LanguageService` in
/// an [Rc](std::rc::Rc) or [Arc](std::sync::Arc) to reuse it, because it
/// already uses an `Arc` internally.
