Struct Signature 

pub struct Signature { /* private fields */ }

Signature produced by an Chio SigningBackend.

Historically this type wrapped a 64-byte Ed25519 signature. It now carries an algorithm-tagged payload internally while preserving byte-identical serialization and construction helpers for the Ed25519 case.

Implementations

impl Signature

pub fn from_bytes(bytes: &[u8; 64]) -> Signature

Create from raw 64-byte Ed25519 signature bytes.

pub fn from_p256_der(bytes: &[u8]) -> Signature

Create a P-256 ECDSA signature from DER-encoded bytes.

pub fn from_p384_der(bytes: &[u8]) -> Signature

Create a P-384 ECDSA signature from DER-encoded bytes.

pub fn from_hex(hex_str: &str) -> Result<Signature, Error>

Create from hex-encoded bytes (with optional 0x prefix).

A bare hex string is interpreted as an Ed25519 signature (64 bytes) for backward compatibility. A p256: or p384: prefix selects ECDSA.

pub fn to_hex(&self) -> String

Hex encoding, with algorithm prefix for non-Ed25519 signatures.

Ed25519 signatures render as a bare 128-character lowercase hex string, byte-identical to the historical format.

pub fn to_bytes(&self) -> [u8; 64]

Raw 64-byte Ed25519 representation.

Mirrors the historical API. For non-Ed25519 signatures returns an all-zero placeholder (such signatures never flow through 64-byte-only consumer paths because those paths are Ed25519-specific on-chain anchoring layers that never see FIPS artifacts).

pub fn algorithm(&self) -> SigningAlgorithm

Which algorithm produced this signature.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Signature

fn deserialize<D>( deserializer: D, ) -> Result<Signature, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Signature

fn eq(&self, other: &Signature) -> 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 Serialize for Signature

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.
