[][src]Struct crc32fast::Hasher

pub struct Hasher { /* fields omitted */ }

Represents an in-progress CRC32 computation.

Methods

impl Hasher[src]

pub fn new() -> Self[src]

Create a new Hasher.

This will perform a CPU feature detection at runtime to select the most optimal implementation for the current processor architecture.

pub fn new_with_initial(init: u32) -> Self[src]

Create a new Hasher with an initial CRC32 state.

This works just like Hasher::new, except that it allows for an initial CRC32 state to be passed in.

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

Process the given byte slice and update the hash state.

pub fn finalize(self) -> u32[src]

Finalize the hash state and return the computed CRC32 value.

pub fn reset(&mut self)[src]

Reset the hash state.

pub fn combine(&mut self, other: &Self)[src]

Combine the hash state with the hash state for the subsequent block of bytes.
