Struct Xxh32 

pub struct Xxh32 { /* private fields */ }

Available on crate feature xxhash only.

Incremental XXH32 state.

Implementations

impl Xxh32

pub const fn new() -> Self

Creates an unseeded XXH32 state.

pub const fn with_seed(seed: u32) -> Self

Creates an XXH32 state with seed.

pub const fn seed(&self) -> u32

Returns the seed used by this state.

pub const fn total_len(&self) -> u64

Returns the number of bytes written so far, saturating at u64::MAX.

pub fn reset(&mut self)

Resets the state while retaining its seed.

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

Adds raw bytes to the hash state.

pub fn digest(&self) -> u32

Returns the XXH32 digest without consuming the state.

impl Write for Xxh32

Available on crate feature std only.

fn write(&mut self, input: &[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.
