Struct PeerId 

pub struct PeerId(/* private fields */);

Peer identity. Wraps a fixed-capacity Multihash<64> so overlays pick their own digest algorithm. Same wire shape as libp2p_identity::PeerId; bytes round-trip without translation.

Implementations

impl PeerId

pub const IDENTITY: u64 = 0x00

Multihash code for identity (raw bytes, no hashing).

pub const SHA2_256: u64 = 0x12

Multihash code for sha2-256.

pub const fn from_multihash(mh: Multihash<64>) -> PeerId

Construct from a multihash directly.

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

Parse the canonical multihash byte form (varint(code) ++ varint(size) ++ digest). Wire-format compatible with libp2p.

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

Canonical multihash byte form, matches libp2p’s PeerId::to_bytes.

pub fn code(&self) -> u64

Multihash algorithm code (e.g. 0x00 identity, 0x12 sha2-256).

pub fn digest(&self) -> &[u8]

Raw digest bytes (after the multihash code + size prefix).

pub fn as_multihash(&self) -> &Multihash<64>

Borrow the inner multihash.

pub fn as_identity_u64(&self) -> Option<u64>

Recover the inner u64 of a PeerId::from(u64). Returns None for non-identity-coded or non-8-byte digests.

Trait Implementations

impl Clone for PeerId

fn clone(&self) -> PeerId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PeerId

impl Debug for PeerId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PeerId

fn deserialize<__D>( __deserializer: __D, ) -> Result<PeerId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PeerId

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

Base58btc-encoded multihash; matches libp2p’s PeerId::to_base58.

impl Eq for PeerId

impl From<u64> for PeerId

fn from(value: u64) -> PeerId

Test convenience: wraps the u64 as an 8-byte identity-coded multihash. Not for production identity — use PeerId::from_multihash / from_bytes for keyed identities.

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,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PeerId

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

Tests for self and other values to be equal, and is used by ==.

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

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for PeerId

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
