Keccak

Examples

use zeros::Hash;

let mut keccak = Hash::Shake128.new_keccak();
keccak.update("test");
assert_eq!(
    keccak.finish(),
    &[
        0xd3, 0xb0, 0xaa, 0x9c, 0xd8, 0xb7, 0x25, 0x56,

Implementations

impl Keccak

pub const fn hash(&self) -> &Hash

Gets hash

pub fn update<B>(&mut self, bytes: B) -> usizewhere
    B: AsRef<[u8]>,

Updates new data

Returns length of input bytes.

pub fn update_iter<I, B>(&mut self, iter: I) -> Option<usize>where
    I: IntoIterator<Item = B>,
    B: AsRef<[u8]>,

Updates new data

Returns length of input bytes. If overflow happens, None will be returned.

pub fn finish(self) -> Vec<u8>

Finishes and returns hash

For large output bytes, you should use finish_as_keccak_x(), and collect hash from it.

pub fn finish_as_hex(self) -> String

Finishes and returns hash as a hexadecimal string, in lower-case

For large output bytes, you should use finish_as_keccak_x(), and collect hash from it.

pub fn finish_as_keccak_x(self) -> KeccakX

Finishes as KeccakX

Trait Implementations

impl Clone for Keccak

fn clone(&self) -> Keccak

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Keccak

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

Formats the value using the given formatter.

impl From<&Hash> for Keccak

fn from(hash: &Hash) -> Self

Converts to this type from the input type.

impl From<Hash> for Keccak

fn from(hash: Hash) -> Self

Converts to this type from the input type.

impl PartialEq<Keccak> for Keccak

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Write for Keccak

fn write(&mut self, buf: &[u8]) -> IoResult<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> IoResult<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice<'_>]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn is_write_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Writer has an efficient write_vectored implementation.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_all_vectored(&mut self, bufs: &mut [IoSlice<'_>]) -> Result<(), Error>

🔬This is a nightly-only experimental API. (write_all_vectored)

Attempts to write multiple buffers into this writer.

fn write_fmt(&mut self, fmt: Arguments<'_>) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Selfwhere
    Self: Sized,

Creates a “by reference” adapter for this instance of Write.
