Struct sp_core::ecdsa::Public

pub struct Public(pub [u8; 33]);

The ECDSA compressed public key.

Tuple Fields

0: [u8; 33]

Implementations

impl Public

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

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<Self, ()>

Create a new instance from the given full public key.

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

impl PartialEq<Public> for Public

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

This method tests for self and other values to be equal, and is used by ==.

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

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.
