Trait sha2::Digest

pub trait Digest {
    type OutputSize: ArrayLength<u8>;
    type BlockSize: ArrayLength<u8>;
    fn input(&mut self, input: &[u8]);
    fn result(self) -> GenericArray<u8, Self::OutputSize>;

    fn block_bytes(&self) -> usize { ... }
    fn block_bits(&self) -> usize { ... }
    fn output_bytes(&self) -> usize { ... }
    fn output_bits(&self) -> usize { ... }
}

The Digest trait specifies an interface common to digest functions

Associated Types

type OutputSize: ArrayLength<u8>

type BlockSize: ArrayLength<u8>

Required Methods

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

Digest input data. This method can be called repeatedly for use with streaming messages.

fn result(self) -> GenericArray<u8, Self::OutputSize>

Retrieve the digest result. This method consumes digest instance.

Provided Methods

fn block_bytes(&self) -> usize

Get the block size in bytes.

fn block_bits(&self) -> usize

Get the block size in bits.

fn output_bytes(&self) -> usize

Get the output size in bytes.

fn output_bits(&self) -> usize

Get the output size in bits.
