Struct ethers_core::types::Signature

pub struct Signature {
    pub r: U256,
    pub s: U256,
    pub v: u64,
}

An ECDSA signature

Fields

r: U256

R value

s: U256

S Value

v: u64

V value in ‘Electrum’ notation.

Implementations

impl Signature

pub fn verify<M, A>(&self, message: M, address: A) -> Result<(), SignatureError> where
    M: Into<RecoveryMessage>,
    A: Into<Address>, 

Verifies that signature on message was produced by address

pub fn recover<M>(&self, message: M) -> Result<Address, SignatureError> where
    M: Into<RecoveryMessage>, 

Recovers the Ethereum address which was used to sign the given message.

Recovery signature data uses ‘Electrum’ notation, this means the v value is expected to be either 27 or 28.

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

Copies and serializes self into a new Vec with the recovery id included

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy 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<'de> Deserialize<'de> for Signature

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Signature

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

impl FromStr for Signature

type Err = SignatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq<Signature> for Signature

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

impl<'a> TryFrom<&'a [u8]> for Signature

fn try_from(bytes: &'a [u8]) -> Result<Self, Self::Error>

Parses a raw signature which is expected to be 65 bytes long where the first 32 bytes is the r value, the second 32 bytes the s value and the final byte is the v value in ‘Electrum’ notation.

type Error = SignatureError
