Struct GameStateSnapshot 

pub struct GameStateSnapshot {
    pub frame: u64,
    pub state: GameStateData,
    pub visual_phash: u64,
    pub state_hash: u64,
}

Game state snapshot with delta encoding

Per spec: Delta encoding achieves 94% overhead reduction (Lavoie [9])

Fields

frame: u64

Frame number when snapshot was taken

state: GameStateData

Game state data

visual_phash: u64

Perceptual hash for visual comparison (more robust than SHA-256)

state_hash: u64

Cryptographic hash for determinism verification

Implementations

impl GameStateSnapshot

pub fn new(frame: u64, state: GameStateData) -> Self

Create a new snapshot

pub const fn with_phash(self, phash: u64) -> Self

Set the perceptual hash
