Struct BearerAuth 

pub struct BearerAuth { /* private fields */ }

Cloneable authentication handle shared by existing gRPC clients.

Refreshing instances publish new tokens through ArcSwap, so clones and already-created crate::GrpcReplicaFactory values observe updates without reconnecting. Dropping the last clone stops the refresh task.

Implementations

impl BearerAuth

pub fn static_token(token: impl Into<String>) -> Self

Create a non-refreshing token handle for tests or controlled deployments.

Prefer google_adc in production.

pub async fn refreshing( source: Arc<dyn AccessTokenSource>, config: RefreshingAuthConfig, ) -> Result<Self, Error>

Create a refreshing handle backed by a custom token source.

Construction fetches and validates the initial token before returning; callers never receive a handle without a usable credential.

pub async fn google_adc(config: RefreshingAuthConfig) -> Result<Self, Error>

Create the production Google Application Default Credentials path.

The credential requests the GCS read/write scope and refreshes in the background according to config.
