Implementations

impl Signature

pub fn verify<M, A>(&self, message: M, address: A) -> Result<(), SignatureError>where
    M: Into<RecoveryMessage>,
    A: Into<H160>,

Verifies that signature on message was produced by address

pub fn recover<M>(&self, message: M) -> Result<H160, 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 recovery_id(&self) -> Result<Id, SignatureError>

Retrieve the recovery ID.

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

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.

const 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 Decodable for Signature

fn decode(buf: &mut &[u8]) -> Result<Signature, DecodeError>

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 Display for Signature

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

Formats the value using the given formatter.

impl Encodable for Signature

fn length(&self) -> usize

fn encode(&self, out: &mut dyn BufMut)

impl From<&Signature> for Vec<u8, Global>

fn from(src: &Signature) -> Vec<u8, Global>

Converts to this type from the input type.

impl From<Signature> for Vec<u8, Global>

fn from(src: Signature) -> Vec<u8, Global>

Converts to this type from the input type.

impl FromStr for Signature

type Err = SignatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Signature, <Signature as FromStr>::Err>

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

impl Hash for Signature

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<Signature> for Signature

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

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

const 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.

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.

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

fn try_from(
    bytes: &'a [u8]
) -> Result<Signature, <Signature as TryFrom<&'a [u8]>>::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

The type returned in the event of a conversion error.

impl Copy for Signature

impl Eq for Signature

impl StructuralEq for Signature

impl StructuralPartialEq for Signature
