Struct NetworkPeerStore 

pub struct NetworkPeerStore { /* private fields */ }

In-memory store for network peer multiaddresses.

The structure holds the mapping between the PeerId and its associated reported multiaddresses recovered from the network discovery mechanism as [Multiaddr].

The store can be combined with other data structures to offer a complete view of the network state in regards to the discovered peers.

Implementations

impl NetworkPeerStore

pub fn new(me: PeerId, my_addresses: HashSet<Multiaddr>) -> Self

pub fn me(&self) -> &PeerId

pub fn has(&self, peer: &PeerId) -> bool

Check whether the peer is present in the network.

pub fn add(&self, peer: PeerId, addresses: HashSet<Multiaddr>) -> Result<()>

Add a new peer with discovered addresses.

The function is smart and extends the existing multiaddresses if the peer is already present.

pub fn get(&self, peer: &PeerId) -> Option<HashSet<Multiaddr>>

Get multiaddresses of a peer.

pub fn remove(&self, peer: &PeerId) -> Result<()>

Remove the peer from the store.

pub fn iter_keys(&self) -> impl Iterator<Item = PeerId> + '_

Iterator over PeerId keys in the store.

Trait Implementations

fn clone(&self) -> NetworkPeerStore

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NetworkPeerStore

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