Struct SessionStore 

pub struct SessionStore { /* private fields */ }

In-memory, lock-free session store keyed by SessionId. The Arc<SessionState> value lets the middleware hand a cheap clone to each request without holding a DashMap shard lock for the whole dispatch.

Cloning a SessionStore is cheap — internally it’s an Arc<Inner>. Pass a clone to the per-process SoloHttpState; the background sweep task holds another clone via Arc::downgrade.

Implementations

impl SessionStore

pub fn new() -> Self

Build a fresh store and spawn the background sweep task on the current tokio runtime. Panics if called outside a tokio runtime context — callers should construct this from inside an async context (e.g. the daemon’s startup, or tokio::runtime::Handle::current()).

pub fn insert(&self, state: SessionState) -> SessionId

Insert a new session and return its assigned id. Each call produces a fresh server-assigned SessionId (UUID v7).

pub fn get(&self, id: &SessionId) -> Option<Arc<SessionState>>

Look up a session by id. Returns None if absent OR expired — expired entries are removed lazily here so the store doesn’t hand out stale state between sweeps. The returned Arc<SessionState>’s last_accessed_at_ms is bumped to “now” on a successful hit.

pub fn delete(&self, id: &SessionId) -> bool

Drop a session by id. Returns true if it was present.

pub fn len(&self) -> usize

Current count of stored sessions. Used by tests + future /v1/health-style readiness probes.

pub fn is_empty(&self) -> bool

True if the store has no sessions.

pub fn sweep_now(&self)

Force one immediate sweep. Used by the background task and by tests that want deterministic sweep behaviour without waiting 60s for the next tick.
