Struct libp2p::PeerId

pub struct PeerId { /* private fields */ }

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

impl PeerId

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

Builds a PeerId from a public key.

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

Parses a PeerId from bytes.

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.

pub fn random() -> PeerId

Available on crate feature rand only.

Generates a random peer ID from a cryptographically secure PRNG.

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

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

Returns a raw bytes representation of this PeerId.

pub fn to_base58(self) -> String

Returns a base-58 encoded string of this PeerId.

Converts to this type from the input type.

impl FromStr for PeerId

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<PeerId, <PeerId as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for PeerId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for PeerId

fn cmp(&self, other: &PeerId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

impl PartialEq for PeerId

fn eq(&self, other: &PeerId) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for PeerId

fn partial_cmp(&self, other: &PeerId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.
