Struct ProxyTokenCache 

pub struct ProxyTokenCache { /* private fields */ }

LRU-bounded cache of access tokens keyed on (local tn_id, remote id_tag).

Uses parking_lot::Mutex (no poisoning) because LruCache::get mutates recency state.

Implementations

impl ProxyTokenCache

pub fn new() -> Self

pub fn with_capacity(capacity: NonZeroUsize) -> Self

pub fn get(&self, tn_id: TnId, id_tag: &str) -> Option<Box<str>>

Returns a cached token if one is still valid; None otherwise.

pub fn insert(&self, tn_id: TnId, id_tag: &str, token: Box<str>)

Inserts a freshly-minted token, deriving its expiry from the JWT’s own exp claim.

pub fn invalidate(&self, tn_id: TnId, id_tag: &str)

Drops the cached token for (tn_id, id_tag). Call after a 401/403 from the remote so the next request mints fresh.

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

impl Default for ProxyTokenCache

fn default() -> Self
