Implementations

impl PeerState

pub fn new() -> Self

pub fn insert(&mut self, peer_id: String, entry: PeerEntry) -> bool

Register a connected peer. Returns false if already known.

pub fn remove(&mut self, peer_id: &str) -> Option<PeerEntry>

Remove a peer by ID. Returns the entry if it existed.

pub fn remove_by_conn(&mut self, conn_id: u64) -> Option<(String, PeerEntry)>

Remove a peer by connection ID (e.g., on unexpected disconnect).

pub fn contains(&self, peer_id: &str) -> bool

Check if a peer is already connected (by peer ID).

pub fn conn_id(&self, peer_id: &str) -> Option<u64>

Get the connection ID for a peer.

pub fn all_conn_ids(&self) -> Vec<u64>

Get all peer connection IDs.

pub fn peer_id_for_conn(&self, conn_id: u64) -> Option<&str>

Look up a peer_id by connection ID.

pub fn len(&self) -> usize

Number of connected peers.

pub fn is_empty(&self) -> bool

Whether there are no connected peers.
