Struct blake2_rfc_bellman_edition::blake2b::Blake2b

pub struct Blake2b { /* fields omitted */ }

State context.

Methods

impl Blake2b

pub fn new(nn: usize) -> Self

Creates a new hashing context without a key.

pub fn with_key(nn: usize, k: &[u8]) -> Self

Creates a new hashing context with a key.

pub fn with_params(nn: usize, key: &[u8], salt: &[u8], persona: &[u8]) -> Self

Creates a new hashing context with the full set of sequential-mode parameters.

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

Updates the hashing context with more data.

pub fn finalize(self) -> Blake2bResult

Consumes the hashing context and returns the resulting hash.

Trait Implementations

impl Clone for Blake2b

Important traits for Blake2b

impl Write for Blake2b

fn clone(&self) -> Blake2b

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blake2b

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

Formats the value using the given formatter.

impl Default for Blake2b

fn default() -> Self

Returns the "default value" for a type.

impl Write for Blake2b

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

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

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

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

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

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

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

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

Attempts to write an entire buffer 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 Self

Creates a "by reference" adaptor for this instance of Write.
