Struct KeyRef 

pub struct KeyRef<'r> { /* private fields */ }

Available on crate feature allow-non-fips only.

A reference to a Key, allowing for efficient key handling without ownership.

Implementations

impl<'r> KeyRef<'r>

pub const fn new(inner: &'r [u8; 32]) -> Self

Creates a new KeyRef from a reference to a 32-byte array.

Arguments

• inner - A reference to a 32-byte array containing the key material.

Example

use wolf_crypto::mac::poly1305::{Key, KeyRef};

let key_bytes = [2u8; 32];
let key = Key::new(key_bytes,);
let key_ref: KeyRef = key.as_ref();

pub const fn copy(&self) -> Key

Creates a copy of the key as a Key.

Returns

A new Key instance containing the same key material.

Example

use wolf_crypto::mac::poly1305::{Key, KeyRef};

let key_ref: KeyRef = (&[7u8; 32]).into();
let owned_key = key_ref.copy();

Trait Implementations

impl<'r> Debug for KeyRef<'r>

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

Formats the value using the given formatter.

impl<'r> From<&'r [u8; 32]> for KeyRef<'r>

fn from(value: &'r [u8; 32]) -> Self

Converts a reference to a 32-byte array into a KeyRef.

Arguments

• value - A reference to a 32-byte array containing the key material.

Example

use wolf_crypto::mac::poly1305::{Key, KeyRef};

let key_ref = KeyRef::from(&[2u8; 32]);

impl<'r> TryFrom<&'r [u8]> for KeyRef<'r>

fn try_from(value: &'r [u8]) -> Result<Self, Self::Error>

Attempts to convert a slice of bytes into a KeyRef.

Arguments

• value - A slice of bytes to convert.

Errors

Returns TryFromSliceError if the slice length is not exactly 32 bytes.

Example

use wolf_crypto::mac::poly1305::KeyRef;

let key_slice = &[5u8; 32];
let key_ref = KeyRef::try_from(key_slice).unwrap();

type Error = TryFromSliceError

The type returned in the event of a conversion error.
