Struct multihash::IdentityHasher

pub struct IdentityHasher<const S: usize> { /* private fields */ }

Identity hasher with a maximum size.

Panics

Panics if the input is bigger than the maximum size.

Trait Implementations

impl<const S: usize> Debug for IdentityHasher<S>

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

Formats the value using the given formatter.

impl<const S: usize> Default for IdentityHasher<S>

fn default() -> Self

Returns the “default value” for a type.

impl<const S: usize> Hasher for IdentityHasher<S>

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

Consume input and update internal state.

fn finalize(&mut self) -> &[u8]

Returns the final digest.

fn reset(&mut self)

Reset the internal hasher state.

impl<const S: usize> Write for IdentityHasher<S>

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_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.
