Struct Signature 

pub struct Signature(/* private fields */);

Signature encoded as RSV components

Implementations

impl Signature

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

Get a slice into the ‘r’ portion of the data.

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]) -> Signature

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) -> Signature

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 Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Default for Signature

fn default() -> Signature

Returns the “default value” for a type.

impl Deref for Signature

type Target = [u8; 65]

The resulting type after dereferencing.

fn deref(&self) -> &<Signature as Deref>::Target

Dereferences the value.

impl DerefMut for Signature

fn deref_mut(&mut self) -> &mut <Signature as Deref>::Target

Mutably dereferences the value.

impl Display for Signature

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

Formats the value using the given formatter.

impl From<[u8; 65]> for Signature

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

Converts to this type from the input type.

impl From<H520> for Signature

fn from(bytes: H520) -> Signature

Converts to this type from the input type.

impl FromStr for Signature

type Err = Error

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 Into<[u8; 65]> for Signature

fn into(self) -> [u8; 65]

Converts this type into the (usually inferred) input type.

impl PartialEq for Signature

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
