Required methods

fn new(key: &GenericArray<u8, Self::KeySize>) -> Self

Create new MAC instance from key with fixed size.

fn input(&mut self, data: &[u8])

Process input data.

fn reset(&mut self)

Reset Mac instance.

fn result(self) -> MacResult<Self::OutputSize>

Obtain the result of a Mac computation as a MacResult and consume Mac instance.

Provided methods

fn new_varkey(key: &[u8]) -> Result<Self, InvalidKeyLength>

Create new MAC instance from key with variable size.

Default implementation will accept only keys with length equal to KeySize, but some MACs can accept range of key lengths.

fn result_reset(&mut self) -> MacResult<Self::OutputSize>

Obtain the result of a Mac computation as a MacResult and reset Mac instance.

fn verify(self, code: &[u8]) -> Result<(), MacError>

Check if code is correct for the processed input.
