Struct RecoverableSignature 

pub struct RecoverableSignature { /* private fields */ }

A secp256k1 ECDSA signature plus the recovery id needed to recover the signing public key.

Serializes to the 65-byte TRON wire format r || s || v, where v is the recovery id (0 or 1).

Implementations

impl RecoverableSignature

pub fn from_signature( sig: &Signature<Secp256k1>, recovery_id: RecoveryId, ) -> RecoverableSignature

Build from a non-recoverable Signature and its RecoveryId.

pub fn from_bytes(bytes: &[u8]) -> Result<RecoverableSignature, SignatureError>

Parse the 65-byte r || s || v representation.

Accepts a v of 0/1 or the Ethereum-style 27/28, normalising to 0/1.

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

The 32-byte r scalar.

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

The 32-byte s scalar.

pub fn v(&self) -> u8

The recovery id (0 or 1).

pub fn to_bytes(&self) -> [u8; 65]

Serialize to the 65-byte r || s || v wire format.

pub fn split( &self, ) -> Result<(Signature<Secp256k1>, RecoveryId), SignatureError>

Recover the non-recoverable Signature and RecoveryId components.

Trait Implementations

impl Clone for RecoverableSignature

fn clone(&self) -> RecoverableSignature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for RecoverableSignature

impl Debug for RecoverableSignature

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

Formats the value using the given formatter.

impl Eq for RecoverableSignature

impl Hash for RecoverableSignature

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

where __H: Hasher,

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 RecoverableSignature

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