Implementations

impl Signature

pub fn recover<T>(&self, data: T) -> Result<PublicKey, SignerError>

where Digest: From<T>,

Recovers the public key which was used to create the signature for the signed data.

pub fn recover_from_digest( &self, digest: &Digest, ) -> Result<PublicKey, SignerError>

Recovers the public key using a precomputed digest.

pub fn recover_message<T>(&self, data: T) -> Result<PublicKey, SignerError>

where Digest: From<T>,

Recovers public key which was used to create the signature for the signed message according to EIP-191 standard.

pub fn verify<T>( &self, public_key: PublicKey, data: T, ) -> Result<(), SignerError>

where Digest: From<T>,

Verifies the signature using the public key and data.

pub fn verify_with_digest( &self, public_key: PublicKey, digest: &Digest, ) -> Result<(), SignerError>

pub fn from_pre_eip155_bytes(bytes: [u8; 65]) -> Option<Signature>

Creates a signature from the bytes in the pre-EIP-155 format (V in {27, 28}).

pub fn into_pre_eip155_bytes(self) -> [u8; 65]

Convert signature into the pre-EIP-155 encoded bytes (V in {27, 28}).

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

impl Copy for Signature

impl Debug for Signature

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

Formats the value using the given formatter.

impl Decode for Signature

Available on crate feature codec only.

fn decode<I>(input: &mut I) -> Result<Signature, Error>

where I: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

Returns the fixed encoded size of the type.

impl<'de> Deserialize<'de> for Signature

Available on crate feature serde only.

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, __derive_more_f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Encode for Signature

Available on crate feature codec only.

fn encode_to<T>(&self, dest: &mut T)

where T: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encoded_size(&self) -> usize

Calculates the encoded size.

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,
