Struct libp2p_identity::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§

source§

impl PeerId

source

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

Builds a PeerId from a public key.

source

pub fn from_bytes(data: &[u8]) -> Result<PeerId, ParseError>

Parses a PeerId from bytes.

source

pub fn from_multihash(multihash: Multihash<64>) -> Result<PeerId, Multihash<64>>

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.

source

pub fn random() -> PeerId

Generates a random peer ID from a cryptographically secure PRNG.

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

source

pub fn to_bytes(self) -> Vec<u8>

Returns a raw bytes representation of this PeerId.

source

pub fn to_base58(self) -> String

Returns a base-58 encoded string of this PeerId.
