Struct avalanche_types::key::secp256k1::signature::Sig

pub struct Sig(pub Signature);

Represents Ethereum-style “recoverable signatures”.

Tuple Fields

0: Signature

Implementations

impl Sig

pub fn from_bytes(b: &[u8]) -> Result<Self>

Loads the recoverable signature from the bytes.

pub fn from_der(
    raw_sig: &[u8],
    digest: &[u8],
    vkey: &VerifyingKey
) -> Result<Self>

Loads the recoverable signature from the DER-encoded bytes, as defined by ANS X9.62–2005 and RFC 3279 Section 2.2.3. ref. https://docs.aws.amazon.com/kms/latest/APIReference/API_Sign.html#KMS-Sign-response-Signature

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

Converts the signature to bytes.

pub fn recover_public_key(&self, digest: &[u8]) -> Result<(Key, VerifyingKey)>

Recovers the public key from the 32-byte SHA256 output message using its signature.

pub fn r(&self) -> U256

pub fn s(&self) -> U256

pub fn v(&self) -> u64

Returns the recovery Id.

Trait Implementations

impl Clone for Sig

fn clone(&self) -> Sig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sig

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

Formats the value using the given formatter.

impl From<Sig> for [u8; 65]

fn from(sig: Sig) -> Self

Converts to this type from the input type.

impl From<Sig> for Signature

fn from(sig: Sig) -> Self

Converts to this type from the input type.

impl From<Signature> for Sig

fn from(sig: Signature) -> Self

Converts to this type from the input type.

impl PartialEq<Sig> for Sig

fn eq(&self, other: &Sig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
