Struct clarity::Signature

pub struct Signature {
    pub v: Uint256,
    pub r: Uint256,
    pub s: Uint256,
}

Fields

v: Uint256

r: Uint256

s: Uint256

Methods

impl Signature

pub fn new(v: Uint256, r: Uint256, s: Uint256) -> Signature

pub fn is_valid(&self) -> bool

pub fn network_id(&self) -> Option<Uint256>

pub fn check_low_s_metropolis(&self) -> Result<(), Error>

pub fn check_low_s_homestead(&self) -> Result<(), Error>

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

Deprecated since 0.1.20:

please use as_bytes instead

Converts a signature into a bytes string.

A signature in binary form consists of 65 bytes where first 32 bytes are "r" in big endian form, next 32 bytes are "s" in big endian form, and at the end there is one byte made of "v".

This also consumes the signature.

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

Extracts signature as bytes.

This supersedes into_bytes as it does not consume the object itself.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Constructs a signature from a bytes string

This is opposite to into_bytes() where a signature is created based on a slice of bytes.

pub fn recover(&self, hash: &[u8]) -> Result<Address, Error>

Recover an address from a signature

This can be called with any arbitrary signature, and a hashed message.

Trait Implementations

impl Eq for Signature

impl Default for Signature

fn default() -> Signature

Returns the "default value" for a 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 ToString for Signature

fn to_string(&self) -> String

Converts the given value to a String.

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 UpperHex for Signature

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

Formats the value using the given formatter.

impl LowerHex for Signature

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

Formats the value using the given formatter.

impl Hash for Signature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where     H: Hasher,

Feeds a slice of this type into the given [Hasher].

impl FromStr for Signature

type Err = Error

The associated error which can be returned from parsing.

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

Constructs a signature back from a string representation

The input string's length should be exactly 130 not including optional "0x" prefix at the beggining.

impl Serialize for Signature

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where     __S: Serializer,

Serialize this value into the given Serde serializer.

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.
