Struct SessionMap 

pub struct SessionMap { /* private fields */ }

Thread-safe map of session keys (typically domains) to proxy bindings.

All operations acquire short-lived locks to minimise contention.

Example

use stygian_proxy::session::SessionMap;
use std::time::Duration;
use uuid::Uuid;

let map = SessionMap::new();
let id = Uuid::new_v4();
map.bind("example.com", id, Duration::from_secs(60));
assert_eq!(map.lookup("example.com"), Some(id));

Implementations

impl SessionMap

pub fn new() -> Self

Create an empty session map.

pub fn lookup(&self, key: &str) -> Option<Uuid>

Look up the proxy bound to key, returning None when no session exists or the existing session has expired.

Expired entries are lazily removed on the next bind or purge_expired call.

pub fn bind(&self, key: &str, proxy_id: Uuid, ttl: Duration)

Bind key to proxy_id with the given TTL. Overwrites any existing session for the same key.

pub fn purge_expired(&self) -> usize

Remove all expired sessions, returning the number removed.

pub fn unbind(&self, key: &str)

Remove a specific session by key.

pub fn active_count(&self) -> usize

Returns the number of active (non-expired) sessions.

Trait Implementations

impl Clone for SessionMap

fn clone(&self) -> SessionMap

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionMap

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

Formats the value using the given formatter.

impl Default for SessionMap

fn default() -> Self

Returns the “default value” for a type.
