Struct Hasher 

pub struct Hasher<K: HashKind>(Hasher, PhantomData<K>);

Tuple Fields

0: Hasher

1: PhantomData<K>

Implementations

impl<K: HashKind> Hasher<K>

pub fn new() -> Self

pub fn update(&mut self, input: &[u8]) -> &mut Self

pub fn finalize(&self) -> Hash<K>

Trait Implementations

impl<K: HashKind> Default for Hasher<K>

fn default() -> Self

Returns the “default value” for a type.

impl<K: HashKind> Write for Hasher<K>

Lets a serializer stream into the hasher without buffering the payload.

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

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

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

Flushes 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, args: Arguments<'_>) -> Result<(), Error>

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

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

where Self: Sized,

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