Struct AuthnCache 

pub struct AuthnCache { /* private fields */ }

Provider-local cache of successful authentication results.

Backed by std::sync::RwLock<HashMap> with lazy eviction, mirroring [CachingPermissionEvaluator]. Entries never outlive their token: the effective lifetime is min(configured TTL, token_exp - now), and hits re-check now < expires_at.

Implementations

impl AuthnCache

pub fn new(options: AuthnCacheOptions) -> Self

pub fn get(&self, key: &AuthnCacheKey) -> Option<AuthenticatedPrincipal>

Look up a cached authentication result.

Returns None on miss OR when the entry’s token has expired (hits re-check now < expires_at).

pub fn insert( &self, key: AuthnCacheKey, principal: AuthenticatedPrincipal, ) -> bool

Insert a minted principal, returning false when it is not stored.

The effective lifetime is min(configured TTL, token_exp - now); a token whose exp has already passed (≤ 0 remaining) is NOT stored. Tokens without an exp claim (e.g. static native tokens) use the configured TTL.

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
