Struct TokenEndpointProvider 

pub struct TokenEndpointProvider { /* private fields */ }

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.

Implementations

impl TokenEndpointProvider

pub fn from_config(config: &Value) -> Result<Self, FaucetError>

Build from a config object with url, optional method (default POST), optional body, token_path (JSONPath), optional expiry_path, and optional expiry_ratio.

Trait Implementations

impl AuthProvider for TokenEndpointProvider

fn credential<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Credential, FaucetError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Return a currently-valid credential, refreshing if needed.

fn invalidate<'life0, 'life1, 'async_trait>( &'life0 self, stale: &'life1 Credential, ) -> Pin<Box<dyn Future<Output = Result<Credential, FaucetError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Force a refresh iff the cached credential still equals stale (compare-and-swap). Multiple connectors that hit a 401 with the same token collapse into a single refresh; callers holding an already-rotated token get the new one without triggering another fetch.

fn provider_name(&self) -> &'static str

Stable, non-empty name for diagnostics and metrics.

impl Debug for TokenEndpointProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
