Struct Hash 

pub struct Hash { /* private fields */ }

A finalized BLAKE2 hash, with constant-time equality.

Implementations

impl Hash

pub fn as_bytes(&self) -> &[u8]

Convert the hash to a byte slice. Note that if you’re using BLAKE2 as a MAC, you need constant time equality, which &[u8] doesn’t provide.

pub fn as_array(&self) -> &[u8; 32]

Convert the hash to a byte array. Note that if you’re using BLAKE2 as a MAC, you need constant time equality, which arrays don’t provide. This panics in debug mode if the length of the hash isn’t OUTBYTES.

pub fn to_hex(&self) -> ArrayString<{ _ }>

Convert the hash to a lowercase hexadecimal ArrayString.

Trait Implementations

impl AsRef<[u8]> for Hash

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Hash

fn clone(&self) -> Hash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Hash

impl Debug for Hash

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

Formats the value using the given formatter.

impl Eq for Hash

impl From<&[u8; 32]> for Hash

fn from(bytes: &[u8; 32]) -> Self

Converts to this type from the input type.

impl From<[u8; 32]> for Hash

fn from(bytes: [u8; 32]) -> Self

Converts to this type from the input type.

impl PartialEq for Hash

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

fn eq(&self, other: &Hash) -> 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.

impl PartialEq<[u8]> for Hash

This implementation is constant time, if the slice is the same length as the hash.

fn eq(&self, other: &[u8]) -> 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.
