Required Methods

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

Update MAC state with the given data.

fn reset(&mut self)

Reset Mac instance.

fn finalize(self) -> Output<Self>

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

Provided Methods

fn finalize_reset(&mut self) -> Output<Self>
