Required methods

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

Create new MAC instance from key with fixed size.

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

Process input data.

pub fn reset(&mut self)

Reset Mac instance.

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

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

Provided methods

pub 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.

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

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

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

Check if code is correct for the processed input.
