22/// Implements a client for the Cloud Natural Language API.
23///
24/// # Example
25/// ```
26/// # tokio_test::block_on(async {
27/// # use google_cloud_language_v2::client::LanguageService;
28/// let client = LanguageService::builder().build().await?;
29/// // use `client` to make requests to the {Codec.APITitle}}.
30/// # gax::Result::<()>::Ok(()) });
31/// ```
32///
33/// # Service Description
34///
35/// Provides text analysis operations such as sentiment analysis and entity
36/// recognition.
37///
38/// # Configuration
39///
40/// To configure `LanguageService` use the `with_*` methods in the type returned
41/// by [builder()][LanguageService::builder]. The default configuration should
42/// work for most applications. Common configuration changes include
43///
44/// * [with_endpoint()]: by default this client uses the global default endpoint
45///   (`https://language.googleapis.com`). Applications using regional
46///   endpoints or running in restricted networks (e.g. a network configured
47//    with [Private Google Access with VPC Service Controls]) may want to
48///   override this default.
49/// * [with_credentials()]: by default this client uses
50///   [Application Default Credentials]. Applications using custom
51///   authentication may need to override this default.
52///
53/// [with_endpoint()]: super::builder::language_service::ClientBuilder::with_endpoint
54/// [with_credentials()]: super::builder::language_service::ClientBuilder::credentials
55/// [Private Google Access with VPC Service Controls]: https://cloud.google.com/vpc-service-controls/docs/private-connectivity
56/// [Application Default Credentials]: https://cloud.google.com/docs/authentication#adc
57///
58/// # Pooling and Cloning
59///
60/// `LanguageService` holds a connection pool internally, it is advised to
61/// create one and the reuse it.  You do not need to wrap `LanguageService` in
62/// an [Rc](std::rc::Rc) or [Arc] to reuse it, because it already uses an `Arc`
63/// internally.
