Required Associated Types

type Output: Copy + Eq + Sized + Send + AsRef<[u8]> + for<'a> TryFrom<&'a [u8]> + Debug

Required Methods

fn new() -> Self

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

fn finalize(self) -> Self::Output

Provided Methods

fn with_output_slice(slice: &[u8]) -> Option<Self>

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.

Implementors

impl Digest for Sha256

Available on crate feature sha2 only.

const DIGEST_NAME: &'static str = "SHA256"

const OUTPUT_LEN: usize = 32usize

const BLOCK_LEN: usize = 64usize

type Output = [u8; 32]

impl<D: Digest> Digest for Hmac<D>

const DIGEST_NAME: &'static str = "HMAC"

const OUTPUT_LEN: usize = D::OUTPUT_LEN

const BLOCK_LEN: usize = D::BLOCK_LEN

type Output = <D as Digest>::Output
