Struct Fingerprint 

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

A 32-byte writer identity (BLAKE3 of an ed25519 public key).

Implementations

impl Fingerprint

pub fn from_bytes(bytes: [u8; 32]) -> Self

Wrap 32 raw bytes that are already a fingerprint.

pub fn from_ed25519_pubkey(pubkey: &[u8]) -> Self

Derive a fingerprint from an ed25519 public key (BLAKE3 of the key bytes). Deterministic and wire-compatible with the mesh.

pub fn as_bytes(&self) -> &[u8; 32]

The raw 32 bytes.

pub fn to_hex(&self) -> String

Lower-case hex (64 chars) — the canonical string form used as the writer column in crate::WriterLog.

pub fn from_hex(s: &str) -> Option<Self>

Parse a 64-char lower-case hex string back into a fingerprint.

Trait Implementations

impl Clone for Fingerprint

fn clone(&self) -> Fingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Fingerprint

impl Debug for Fingerprint

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

Formats the value using the given formatter.

impl Display for Fingerprint

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

Formats the value using the given formatter.

impl Eq for Fingerprint

impl Hash for Fingerprint

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

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 PartialEq for Fingerprint

fn eq(&self, other: &Fingerprint) -> 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.
