Struct LanguageService 

pub struct LanguageService { /* private fields */ }

Implements a client for the Cloud Natural Language API.

Example

let client = LanguageService::builder().build().await?;
// use `client` to make requests to the Cloud Natural Language API.

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(). 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 override this default.
• with_credentials(): by default this client uses Application Default Credentials. Applications using custom authentication may need to override this default.

Pooling and Cloning

LanguageService holds a connection pool internally, it is advised to create one and the reuse it. You do not need to wrap LanguageService in an Rc or Arc to reuse it, because it already uses an Arc internally.

Implementations

impl LanguageService

pub fn builder() -> ClientBuilder

Returns a builder for LanguageService.

let client = LanguageService::builder().build().await?;

pub fn from_stub<T>(stub: T) -> Self

where T: LanguageService + 'static,
