Implementations

impl Signature

pub fn algorithm(&self) -> Algorithm

Returns the signing algorithm.

pub fn from_bytes(algorithm: Algorithm, bytes: &[u8]) -> Result<Self>

Creates a signature from a byte sequence for a given signing algorithm.

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

Returns a byte sequence representing the signature.

pub fn recover(&self, msg: &[u8]) -> Result<Option<PublicKey>>

Returns the recovered public key if supported.

pub fn recover_prehashed(&self, hash: &[u8]) -> Result<Option<PublicKey>>

Returns the recovered public key if supported.

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

Formats the value using the given formatter.

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 Copy for Signature

impl Eq for Signature

impl StructuralPartialEq for Signature
