Struct polkadot_node_network_protocol::PeerId

impl PeerId

pub fn from_public_key(key: &PublicKey) -> PeerId

Checks whether the public key passed as parameter matches the public key of this PeerId.

Returns None if this PeerIds hash algorithm is not supported when encoding the given public key, otherwise Some boolean as the result of an equality check.
