Trait digest::Digest[−][src]

pub trait Digest {
    type OutputSize: ArrayLength<u8>;
    fn new() -> Self;

    fn update(&mut self, data: impl AsRef<[u8]>);

    fn chain_update(self, data: impl AsRef<[u8]>) -> Self;

    fn finalize(self) -> Output<Self>;

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

    fn finalize_into(self, out: &mut Output<Self>);

    fn finalize_into_reset(&mut self, out: &mut Output<Self>);

    fn reset(&mut self);

    fn output_size() -> usize;

    fn digest(data: impl AsRef<[u8]>) -> Output<Self>;
}

The Digest trait specifies an interface common for digest functions.

It's a convenience wrapper around Update, FixedOutput, Reset, Clone, and Default traits. It also provides additional convenience methods.
