Struct ProfileMeCache 

pub struct ProfileMeCache { /* private fields */ }

LRU-bounded cache of /api/me responses keyed on TnId.

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

Implementations

impl ProfileMeCache

pub fn new() -> Self

pub fn with_capacity(capacity: NonZeroUsize) -> Self

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

Returns the cached ETag if one is still valid; None otherwise.

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

Inserts a freshly-computed ETag, stamping its expiry from the configured TTL.

pub fn touch(&self, tn_id: TnId)

Refresh an existing entry’s TTL without recomputing its ETag. Called on a 304 fast-path hit so a continuously-polled tenant stays warm. No-op if the entry is already gone.

This makes expiry sliding: a steady poll stream keeps an entry alive indefinitely, so the 30s TTL no longer bounds staleness for a write path that forgets to call invalidate. That is acceptable — explicit invalidate is the real freshness mechanism; the TTL is only a backstop for a genuinely idle entry.

pub fn invalidate(&self, tn_id: TnId)

Drops the cached entry for tn_id. Call immediately after any write that can change what /api/me returns (profile fields, signing keys).
