Implementations

impl AuthClientBuilder

pub fn new(project_id: impl Into<String>) -> Self

Starts building a client for the given Firebase project id.

pub fn service_account_key(self, key: ServiceAccountKey) -> Self

Authenticates using an explicit service account key.

pub fn application_default_credentials(self) -> Self

Authenticates using Application Default Credentials, resolved on first use: the GOOGLE_APPLICATION_CREDENTIALS environment variable, gcloud user credentials, or the GCE/Cloud Run metadata server, in that order (see gcp_auth::provider).

pub fn use_emulator(self, host: impl Into<String>) -> Self

Targets a Firebase Auth Emulator at host (e.g. localhost:9099) instead of production Firebase.

If not called, the client still auto-detects the FIREBASE_AUTH_EMULATOR_HOST environment variable in Self::build.

Supplies a custom reqwest::Client, e.g. for testing.

pub fn build(self) -> Result<AuthClient, AuthError>
