pub struct Hasher { /* private fields */ }
Expand description

Represents an in-progress CRC32 computation.

Implementations

Create a new Hasher.

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

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.

Create a new Hasher with an initial CRC32 state.

As new_with_initial, but also accepts a length (in bytes). The resulting object can then be used with combine to compute crc(a || b) from crc(a), crc(b), and len(b).

Process the given byte slice and update the hash state.

Finalize the hash state and return the computed CRC32 value.

Reset the hash state.

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