Struct crc32fast::Hasher

pub struct Hasher { /* fields omitted */ }

[−] Expand description

Represents an in-progress CRC32 computation.

Implementations

impl Hasher[−]

pub fn new() -> Self[−]

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[−]

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])[−]

Process the given byte slice and update the hash state.

pub fn finalize(self) -> u32[−]

Finalize the hash state and return the computed CRC32 value.

pub fn reset(&mut self)[−]

Reset the hash state.

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

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