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 id.

pub fn from_compact(rec_id: RecoveryId, ret: [u8; 64]) -> Self

Construct a new Signature from compact serialize slice and rec_id

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

Construct a new Signature from rsv.

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

Construct a new Signature from slice.

pub fn is_valid(&self) -> bool

Check if each component of the signature is in range.

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

Converts compact signature to a recoverable signature

pub fn recover(&self, message: &Message) -> Result<Pubkey, Error>
