Struct Digest

pub struct Digest {
    pub bytes: ArrayVec<[u8; 64]>,
}

A finalized BLAKE2 hash.

Digest supports constant-time equality checks, for cases where BLAKE2 is being used as a MAC. It uses an ArrayVec to hold various digest lengths without needing to allocate on the heap.

Fields

bytes: ArrayVec<[u8; 64]>

Implementations

impl Digest

pub fn hex(&self) -> ArrayString<[u8; 128]>

Convert the digest to a hexadecimal string. Because we know the maximum length of the string in advance (2 * OUTBYTES), we can use an ArrayString to avoid allocating.

Trait Implementations

impl Clone for Digest

fn clone(&self) -> Digest

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Digest

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Digest

This implementation is constant time, if the two digests are the same length.

fn eq(&self, other: &Digest) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
