Module auth 

Available on crate feature auth only.

Single-flight OAuth2 / token-endpoint auth providers (enable the auth feature). Share one across connectors via with_auth_provider or the CLI auth: { ref } catalog.

Structs

OAuth2ClientCredentialsProvider

OAuth2 client_credentials grant provider.

OAuth2RefreshProvider

OAuth2 refresh_token grant provider with refresh-token rotation capture.

StaticProvider

Returns a fixed Credential forever. Useful for pre-minted tokens whose lifetime exceeds the run, or for sharing one static bearer token across many connectors.

TokenEndpointProvider

Fetches a token from an arbitrary endpoint, extracts it via token_path (JSONPath), and caches it with optional expiry tracking. Single-flight refresh via an internal Mutex.

Constants

DEFAULT_EXPIRY_RATIO

Default fraction of expires_in after which a token is proactively refreshed. A token with expires_in = 3600 is refreshed after 3240 s.

Functions

build_provider

Build a shared AuthProvider from a { type, config } spec — the shape used by the CLI’s top-level auth: catalog.
