Implementations

impl Blake2b256

pub const CODE: Code

The code of the Blake2-256 hasher, 0xb220.

pub fn digest(data: &[u8]) -> Multihash

Hash some input and return the Multihash digest.

Trait Implementations

impl Clone for Blake2b256

fn clone(&self) -> Blake2b256

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blake2b256

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

Formats the value using the given formatter.

impl Default for Blake2b256

fn default() -> Self

Returns the “default value” for a type.

impl MultihashDigest<Code> for Blake2b256

fn code(&self) -> Code

The Mutlihash byte value.

fn digest(&self, data: &[u8]) -> Multihash

Hash some input and return the digest.

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

Digest data, updating the internal state.

fn result(self) -> Multihash

Retrieve the computed MultihashGeneric, consuming the hasher.

fn digest(data: &[u8]) -> Multihash

Hash some input and return the digest.

impl Write for Blake2b256

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.

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

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

pub 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.

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

Attempts to write an entire buffer into this writer.

pub 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.

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

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

pub fn by_ref(&mut self) -> &mut Self

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