Struct CachedStore 

pub struct CachedStore<S: CredentialStore> { /* private fields */ }

Caching wrapper around any CredentialStore.

Use CachedStore::new with an explicit TTL. Passing ttl = Duration::from_secs(0) disables caching and makes every get() hit the inner store directly — the wrapper simply proxies in that case.

Implementations

impl<S: CredentialStore> CachedStore<S>

pub fn new(inner: S, ttl: Duration) -> Self

Wrap inner with a cache that keeps successful reads for ttl.

Cache misses (key not found) are not cached — we do not want to pin a stale negative result when credentials are rotated in behind the scenes.

pub fn invalidate_all(&self)

Drop every cached entry (wiping their buffers). Useful for explicit logout flows.

pub fn invalidate(&self, key: &str)

Drop a single cached entry.
