Implementations

impl PublicKey

pub fn to_address(&self, format: AddressFormat) -> Address

Returns the address of a public key.

impl PublicKey

pub fn algorithm(&self) -> Algorithm

Returns the signing algorithm.

pub fn from_bytes( algorithm: Algorithm, bytes: &[u8], ) -> Result<PublicKey, Error>

Creates a public key from a byte sequence for a given signing algorithm.

pub fn to_bytes(&self) -> Vec<u8>

Returns a byte sequence representing the public key.

pub fn to_uncompressed_bytes(&self) -> Vec<u8>

Returns an uncompressed byte sequence representing the public key.

pub fn verify(&self, msg: &[u8], sig: &Signature) -> Result<(), Error>

Verifies a signature.

Trait Implementations

impl Clone for PublicKey

fn clone(&self) -> PublicKey

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PublicKey

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for PublicKey

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Copy for PublicKey
