Struct MockDigest 

pub struct MockDigest { /* private fields */ }

A mock of the Update trait

Instead of actually hashing its input, it just collects all bytes and stores them.

Examples

use digest::Update;
use mock_digest::MockDigest;

let mut mock_digest = MockDigest::default();

mock_digest.update(&[1, 2]);
mock_digest.update(&[3]);

assert_eq!(&[1, 2, 3], mock_digest.as_ref());

Trait Implementations

impl AsRef<[u8]> for MockDigest

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

Gets collected bytes as a slice.

impl Clone for MockDigest

fn clone(&self) -> MockDigest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MockDigest

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

Formats the value using the given formatter.

impl Default for MockDigest

fn default() -> MockDigest

Returns the “default value” for a type.

impl From<MockDigest> for Vec<u8>

fn from(src: MockDigest) -> Self

Extracts collected bytes.

impl Hash for MockDigest

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Reset for MockDigest

fn reset(&mut self)

Resets hasher to initial state, discarding all stored bytes.

impl Update for MockDigest

fn update(&mut self, data: &[u8])

Collect and store bytes

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

where Self: Sized,

Digest input data in a chained manner.
