Incremental seed-zero XXH64 state for zstd frame checksum validation.

Details

Xxh64.make creates fixed storage. Xxh64.updateByte accepts decoded bytes, and Xxh64.finish returns the complete hash without changing the state. The decoder compares its low 32 bits.

Import as Xxh64 with import silk.support.zstd_checksum { Xxh64 }.

Public declarations: 1.

Xxh64

pub struct Xxh64

An allocation-free seed-zero checksum state with a 32-byte partial stripe.

Associated function Xxh64.make

pub fn make() -> Xxh64

Creates an empty seed-zero checksum state without allocating storage.

Method Xxh64.updateByte

pub fn updateByte<'life0>(self: &'life0 mut Xxh64, value: u8) -> ()

Adds one decoded byte without allocating storage.

Gotchas

The caller must reject input that would make the total byte count exceed u64.MAX.

Method Xxh64.finish

pub fn finish<'life0>(self: &'life0 Xxh64) -> u64

Returns the seed-zero XXH64 digest without changing or consuming the state.
