Struct FlowProvider 

pub struct FlowProvider { /* private fields */ }

A composable multi-step auth flow provider.

Implementations

impl FlowProvider

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

Build a flow provider from its config block.

Trait Implementations

impl AuthProvider for FlowProvider

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 request_auth<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _method: &'life1 str, _url: &'life2 str, _query: &'life3 BTreeMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<RequestAuth, FaucetError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Richer per-request auth for multi-step flows (#511): credential placements across header / query / cookie / body plus an optional dynamic base-URL override.

fn reauth_statuses(&self) -> &[u16]

HTTP status codes on which the connector should force a re-auth (via invalidate) and retry the request once.

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

Stable, non-empty name for diagnostics and metrics.

fn sign_request<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _method: &'life1 str, _url: &'life2 str, _query: &'life3 BTreeMap<String, String>, ) -> Pin<Box<dyn Future<Output = Result<Option<Credential>, FaucetError>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, Self: 'async_trait,

Per-request signing hook (OAuth1 and similar, #496).

impl Debug for FlowProvider

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

Formats the value using the given formatter.
