Implementations

source

impl Signature

source

pub fn from_raw(data: [u8 ; 65]) -> Signature

A new instance from the given 65-byte data.

NOTE: No checking goes on to ensure this is a real signature. Only use it if you are certain that the array actually is a signature. GIGO!

source

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

A new instance from the given slice that should be 65 bytes long.

NOTE: No checking goes on to ensure this is a real signature. Only use it if you are certain that the array actually is a signature. GIGO!

source

pub fn recover<M: AsRef<[u8 ]>>(&self, message: M) -> Option<Public>

Recover the public key from this signature and a message.
