Struct fuels_core::signature::Signature

pub struct Signature {
    pub compact: Bytes64,
}

An ECDSA signature. Encoded as:

|    32 bytes   ||           32 bytes           |
[256-bit r value][1-bit v value][255-bit s value]

The encoding of the signature was derived from Compact Signature Representation.

Signatures are represented as the r and s (each 32 bytes), and v (1-bit) values of the signature. r and s take on their usual meaning while v is used for recovering the public key from a signature more quickly.

Fields

compact: Bytes64

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 Fuel address which was used to sign the given message. Note that this message can be either the original message or its digest (hashed message). Both can be used to recover the address of the signature.

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 Display for Signature

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

Formats the value using the given formatter.

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

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

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

This method tests for !=.

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

type Error = SignatureError

The type returned in the event of a conversion error.

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

Performs the conversion.
