Implementations

source

impl Signature

source

pub fn from_raw(data: [u8 ; 64]) -> Signature

A new instance from the given 64-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 64 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 from_h512(v: H512) -> Signature

A new instance from an H512.

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!
