Enum KeyRef 

pub enum KeyRef<'r> {
    B128(&'r [u8; 16]),
    B256(&'r [u8; 32]),
}

Available on crate feature allow-non-fips only.

Represents either a 128-bit or 256-bit ChaCha20 key.

Variants

B128(&'r [u8; 16])

128-bit key.

B256(&'r [u8; 32])

256-bit key.

Implementations

impl<'r> KeyRef<'r>

pub const fn copy(&self) -> Key

Copies the underlying key material into a new Key instance.

impl<'r> KeyRef<'r>

pub const fn new_128(key: &'r [u8; 16]) -> Self

Creates a new 128-bit key

pub const fn new_256(key: &'r [u8; 32]) -> Self

Creates a new 256-bit key

pub const fn len(&self) -> u32

Returns the length of the key in bytes

pub const fn ident(&self) -> &'static str

Returns a friendly identifier for the key.

Returns

• 256 bit key: "KeyRef::256"
• 128 bit key: "KeyRef::128"

pub const fn as_slice(&self) -> &[u8]

Returns a slice of the key data

Trait Implementations

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

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

This writes the following to the Formatter (depending on the variant):

• 256 bit key: "KeyRef::256"
• 128 bit key: "KeyRef::128"

impl<'r> Display for KeyRef<'r>

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

This writes the following to the Formatter (depending on the variant):

• 256 bit key: "KeyRef::256"
• 128 bit key: "KeyRef::128"

impl<'r> From<&'r [u8; 16]> for KeyRef<'r>

impl<'r> GenericKey for KeyRef<'r>

fn slice(&self) -> &[u8]

Returns a slice of the key data

fn size(&self) -> u32

Returns the size of the key in bytes
