Struct SessionStore 

pub struct SessionStore { /* private fields */ }

Token-keyed pool of live sessions. Threaded through AppState as Arc<SessionStore> so the idle reaper (a detached thread) shares the same map as request handlers.

Implementations

impl SessionStore

pub fn new(max_sessions: usize, idle_timeout: Duration) -> Self

New store allowing up to max_sessions concurrent sessions, each evicted after idle_timeout of inactivity.

pub fn create(&self, session: MongrelSession, owner: String) -> Option<String>

Register a new session under a fresh opaque token. Returns the token, or None if the store is at capacity (caller maps this to HTTP 503).

pub fn get(&self, token: &str, owner: &str) -> Option<Arc<SessionEntry>>

Look up a session by token, verifying the caller owns it and the session is not closed. Returns a cloned Arc<SessionEntry> (the store lock is released immediately; the caller holds the entry’s per-session lock for the request duration, and must re-check is_closed() after locking). Returns None for an unknown token, an ownership mismatch, or a closed session.

pub fn close(&self, token: &str, owner: &str) -> bool

Remove and drop a session, marking it closed first so any request that already holds an Arc aborts after acquiring the lock. Returns whether a session was removed. Rejects non-owners.

pub fn sweep_idle(&self) -> usize

Evict every session idle for longer than the configured timeout, skipping any session with an in-flight request (per-session lock held). Called periodically by spawn_session_reaper. Returns the count evicted.

pub fn len(&self) -> usize

Current number of live sessions (diagnostics / tests).

pub fn is_empty(&self) -> bool
