Implementations

impl Public

pub fn from_raw(data: [u8; 33]) -> Public

A new instance from the given 33-byte data.

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

pub fn from_full(full: &[u8]) -> Result<Public, ()>

Create a new instance from the given full public key.

This will convert the full public key into the compressed format.
