Struct InnerPeer 

struct InnerPeer<D: SharedUnlockDriver> {
    driver: D,
    ipc_client: Arc<dyn IpcClient>,
    states: Mutex<HashMap<UserId, TimestampedLockState>>,
    active_peers: ActivePeerTracker,
    timing: SharedUnlockTiming,
    destinations: Mutex<HashMap<UserId, HashSet<SharedUnlockClient>>>,
}

Inner implementation of the peer, containing the actual state and logic. The outer SharedUnlockPeer is a thin wrapper around an Arc to allow for shared ownership across async tasks.

Fields

driver: D

ipc_client: Arc<dyn IpcClient>

states: Mutex<HashMap<UserId, TimestampedLockState>>

This device’s view of each user’s lock state.

active_peers: ActivePeerTracker

timing: SharedUnlockTiming

destinations: Mutex<HashMap<UserId, HashSet<SharedUnlockClient>>>

Per user, the client kinds this peer is allowed to sync that user to. A user is absent until SharedUnlockPeer::set_destinations is called for it, so a user is shared with nothing until its client opts in.
