Struct libp2p_core::PeerId

source ·
pub struct PeerId { /* private fields */ }
Expand description

Identifier of a peer of the network.

The data is a CIDv0 compatible multihash of the protobuf encoded public key of the peer as specified in specs/peer-ids.

Implementations§

Builds a PeerId from a public key.

Parses a PeerId from bytes.

Tries to turn a Multihash into a PeerId.

If the multihash does not use a valid hashing algorithm for peer IDs, or the hash value does not satisfy the constraints for a hashed peer ID, it is returned as an Err.

Tries to extract a PeerId from the given Multiaddr.

In case the given Multiaddr ends with /p2p/<peer-id>, this function will return the encapsulated PeerId, otherwise it will return None.

Generates a random peer ID from a cryptographically secure PRNG.

This is useful for randomly walking on a DHT, or for testing purposes.

Returns a raw bytes representation of this PeerId.

Returns a base-58 encoded string of this 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.
