Enum SignatureType 

pub enum SignatureType {
    Ed25519,
    MetamorphicHybrid,
}

A note signature algorithm, identified by its C2SP signed-note type identifier (one or more bytes).

SignatureType::Ed25519 (0x01) is the classical, witness-compatible algorithm. SignatureType::MetamorphicHybrid (the 0xff-escaped HYBRID_SIG_IDENTIFIER) is the additive post-quantum composite. Other assigned bytes (ECDSA 0x02, the cosignature types, etc.) are recognized as unknown and their lines are ignored by verifiers.

Variants

Ed25519

0x01 — Ed25519 over the note text (RFC 8032).

MetamorphicHybrid

HYBRID_SIG_IDENTIFIER — the metamorphic-crypto ML-DSA + classical composite (strict-AND), over the note text under HYBRID_SIG_CONTEXT.

Implementations

impl SignatureType

pub fn type_identifier(self) -> &'static [u8]

The on-the-wire type identifier (one byte for Ed25519, the multi-byte 0xff-escaped label for the hybrid composite).

Trait Implementations

impl Clone for SignatureType

fn clone(&self) -> SignatureType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SignatureType

impl Debug for SignatureType

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

Formats the value using the given formatter.

impl Eq for SignatureType

impl Hash for SignatureType

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 SignatureType

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