Implementations

impl X25519PublicKey

pub const KEY_SIZE: usize = 32usize

pub const fn from_data(data: [u8; 32]) -> Self

Restore an X25519PublicKey from a fixed-size array of bytes.

pub fn from_data_ref(data: impl AsRef<[u8]>) -> Result<Self>

Restore an X25519PublicKey from a reference to an array of bytes.

pub fn data(&self) -> &[u8; 32]

Get a reference to the fixed-size array of bytes.

pub fn from_hex(hex: impl AsRef<str>) -> Self

Trait Implementations

impl AsRef<X25519PublicKey> for X25519PublicKey

fn as_ref(&self) -> &X25519PublicKey

Converts this type into a shared reference of the (usually inferred) input type.

impl CBORTagged for X25519PublicKey

fn cbor_tags() -> Vec<Tag>

fn untagged_cbor(&self) -> CBOR

Returns the untagged CBOR encoding of this instance.

fn tagged_cbor(&self) -> CBOR

Returns the tagged CBOR encoding of this instance.

fn tagged_cbor_data(&self) -> Vec<u8>

impl Clone for X25519PublicKey

fn clone(&self) -> X25519PublicKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for X25519PublicKey

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

impl PartialEq for X25519PublicKey

fn eq(&self, other: &X25519PublicKey) -> 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.
