Struct CachingCredentials 

pub struct CachingCredentials { /* private fields */ }

A credential store that serves the latest minted value for each provider-backed id, and pre-seeded static secrets for the rest. The data plane calls CredentialStore::resolve (sync); minting happens out of band in Self::refresh_due.

Implementations

impl CachingCredentials

pub fn new( static_secrets: HashMap<String, Secret>, providers: HashMap<String, Arc<dyn CredentialProvider>>, ) -> Self

A store with the given static secrets and minting providers. Ids must be disjoint; a provider id shadows a static one of the same name.

pub fn insert_static(&self, id: impl Into<String>, secret: Secret)

Register or replace a static secret (used in tests and for late-bound config).

pub async fn refresh_due(&self, now_ms: u64) -> Vec<String>

Mint every provider-backed credential whose cached value is missing or within its refresh skew of expiry. Returns the ids (re)minted. Errors are logged and skipped so one failing provider doesn’t stall the others.

Trait Implementations

impl CredentialStore for CachingCredentials

fn resolve(&self, id: &str) -> Option<Secret>

The real secret for id, or None if no such credential is configured.
