Struct SessionStore 

pub struct SessionStore { /* private fields */ }

Thread-safe in-memory session store with TTL-based expiry.

Cloning is cheap — all clones share the same backing map via Arc. Place one instance in your application state and share it across handlers.

Implementations

impl SessionStore

pub fn new(ttl_secs: u64) -> Self

Create a new store where sessions expire ttl_secs seconds after creation.

pub fn create(&self) -> Session

Create a new empty session with a generated ID, insert it into the store, and return it. Mutate the session then call save.

pub fn create_with_id(&self, id: String) -> Session

Create a new empty session using id (caller supplies the value, e.g. from a CSPRNG). Inserts the session and returns it.

pub fn load(&self, id: &str) -> Option<Session>

Load a session by ID. Returns None if unknown or expired.

pub fn save(&self, session: &Session)

Persist a session’s data back to the store. No-op if the session ID is no longer present (e.g. already destroyed or expired and purged).

pub fn destroy(&self, id: &str)

Delete a session immediately. Also clear the client cookie using destroy_cookie.

pub fn purge_expired(&self)

Remove all sessions whose TTL has elapsed. Call periodically to reclaim memory (e.g. once per minute from a background thread).

pub fn len(&self) -> usize

Number of sessions in the store, including expired but not yet purged.

pub fn is_empty(&self) -> bool

true if the store contains no sessions.

Trait Implementations

impl Clone for SessionStore

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
