Digest

pub struct Digest {
  state : UInt64
}

FNV-1a 64 位状态哈希。

用途：回滚同步里两侧每 N 帧交换一次哈希，不一致即 desync。只依赖整数运算与固定的字节序，跨后端天然一致。

Digest::feed_byte

source

fn Digest::feed_byte(self : Digest, byte : Int) -> Unit

喂入一个字节（低 8 位有效）。

Digest::feed_bytes

source

fn Digest::feed_bytes(self : Digest, bytes : Bytes) -> Unit

喂入一段字节。

Digest::feed_i64

source

fn Digest::feed_i64(self : Digest, value : Int64) -> Unit

喂入 64 位有符号整数（按位重解释）。

Digest::feed_u64

source

fn Digest::feed_u64(self : Digest, value : UInt64) -> Unit

喂入 64 位整数，按小端逐字节处理（字节序固定，避免平台差异）。

Digest::finish

source

fn Digest::finish(self : Digest) -> UInt64

取出当前哈希值。

Digest::new

source

fn Digest::new() -> Digest

hash_u64

source

fn hash_u64(value : UInt64) -> UInt64

一次性哈希一个 64 位值。
