Struct ethkey::Signature

#[repr(C)]
pub struct Signature(_);

Signature encoded as RSV components

Methods

impl Signature

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn r(&self) -> &[u8]

Get a slice into the 'r' portion of the data.

Important traits for &'a [u8]

impl<'a> Read for &'a [u8]impl<'a> Write for &'a mut [u8]

pub fn s(&self) -> &[u8]

Get a slice into the 's' portion of the data.

pub fn v(&self) -> u8

Get the recovery byte.

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

Encode the signature into RSV array (V altered to be in "Electrum" notation).

pub fn from_electrum(data: &[u8]) -> Self

Parse bytes as a signature encoded as RSV (V in "Electrum" notation). May return empty (invalid) signature if given data has invalid length.

pub fn from_rsv(r: &H256, s: &H256, v: u8) -> Self

Create a signature object from the sig.

pub fn is_low_s(&self) -> bool

Check if this is a "low" signature.

pub fn is_valid(&self) -> bool

Check if each component of the signature is in range.

Trait Implementations

impl PartialEq for Signature

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

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

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

This method tests for !=.

impl Eq for Signature

impl Debug for Signature

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

Formats the value using the given formatter.

impl Display for Signature

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

Formats the value using the given formatter.

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>

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

impl Default for Signature

fn default() -> Self

Returns the "default value" for a type.

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 Clone for Signature

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<[u8; 65]> for Signature

fn from(s: [u8; 65]) -> Self

impl Deref for Signature

type Target = [u8; 65]
