Trait Mac

pub trait Mac: Clone {
    type OutputSize: ArrayLength<u8>;

    // Required methods
    fn update(&mut self, data: &[u8]);
    fn reset(&mut self);
    fn finalize(self) -> Output<Self>;

    // Provided methods
    fn finalize_reset(&mut self) -> Output<Self> { ... }
    fn verify(self, tag: &[u8]) -> Result<(), MacError> { ... }
}

The Mac trait defines methods for a Message Authentication algorithm.

Required Associated Types

type OutputSize: ArrayLength<u8>

Output size of the [Mac]

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>

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

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

Check if tag/code value is correct for the processed input.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
