Struct PublicKeyFingerprint 

pub struct PublicKeyFingerprint<T = String>(/* private fields */);

A full BLAKE3 fingerprint for an Ed25519 public key.

This is deliberately distinct from IdentifierHash at API boundaries: a public-key fingerprint must not be accepted where a token verifier or another identifier happens to have the same representation.

Implementations

impl<T> PublicKeyFingerprint<T>

pub const fn as_inner(&self) -> &T

Borrow the wrapped representation.

pub fn into_inner(self) -> T

Consume the fingerprint and return its wrapped representation.

pub fn map<U>(self, map: impl FnOnce(T) -> U) -> PublicKeyFingerprint<U>

Transform the representation of a validated fingerprint.

This constructs non-default generic specializations without exposing an unchecked constructor for the semantic fingerprint type.

impl PublicKeyFingerprint<String>

pub fn from_public_key(public_key: &PublicKey) -> Self

Derive a fingerprint from a validated Ed25519 public key.

pub fn from_ed25519_hex(value: &str) -> CryptoResult<Self>

Parse a bare or ed25519:-prefixed hexadecimal key and fingerprint it.

Errors

Returns an error when the input is not a 32-byte Ed25519 public key.

pub fn as_str(&self) -> &str

Borrow the blake3:<lowercase hex> representation.
