Trait AccessTokenCredentialsProvider 

pub trait AccessTokenCredentialsProvider: CredentialsProvider + Debug {
    // Required method
    fn access_token(
        &self,
    ) -> impl Future<Output = Result<AccessToken, CredentialsError>> + Send;
}

A trait for credential types that can provide direct access to an access token.

This trait is primarily intended for interoperability with other libraries that require a raw access token, or for calling Google Cloud APIs that are not yet supported by the SDK.

Required Methods

fn access_token( &self, ) -> impl Future<Output = Result<AccessToken, CredentialsError>> + Send

Asynchronously retrieves an access token.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
