Struct yup_oauth2::ApplicationDefaultCredentialsAuthenticator

pub struct ApplicationDefaultCredentialsAuthenticator;

Create an authenticator that uses a application default credentials.

    let opts = ApplicationDefaultCredentialsFlowOpts::default();
    let authenticator = match ApplicationDefaultCredentialsAuthenticator::builder(opts).await {
        ApplicationDefaultCredentialsTypes::InstanceMetadata(auth) => auth
            .build()
            .await
            .expect("Unable to create instance metadata authenticator"),
        ApplicationDefaultCredentialsTypes::ServiceAccount(auth) => auth
            .build()
            .await
            .expect("Unable to create service account authenticator"),
    };

Implementations

impl ApplicationDefaultCredentialsAuthenticator

pub async fn from_environment() -> Result<ServiceAccountFlowOpts, VarError>

Try to build ServiceAccountFlowOpts from the environment

pub async fn builder(
    opts: ApplicationDefaultCredentialsFlowOpts
) -> ApplicationDefaultCredentialsTypes<DefaultHyperClient>

Available on crate features hyper-rustls or hyper-tls only.

Use the builder pattern to deduce which model of authenticator should be used: Service account one or GCE instance metadata kind

pub async fn with_client<C>(
    opts: ApplicationDefaultCredentialsFlowOpts,
    client: C
) -> ApplicationDefaultCredentialsTypes<C> where
    C: HyperClientBuilder, 

Use the builder pattern to deduce which model of authenticator should be used and allow providing a hyper client
