Struct SnapshotBuffer 

pub struct SnapshotBuffer { /* private fields */ }

Ring buffer of recent game-state snapshots.

Used on both client (for interpolation) and server (for lag compensation).

Implementations

impl SnapshotBuffer

pub const DEFAULT_MAX_LEN: usize = 64

pub fn new(max_len: usize) -> Self

pub fn default() -> Self

pub fn push(&mut self, snap: GameStateSnapshot)

Push a new snapshot; evict the oldest if at capacity.

pub fn latest(&self) -> Option<&GameStateSnapshot>

Most recent snapshot.

pub fn oldest(&self) -> Option<&GameStateSnapshot>

Oldest stored snapshot.

pub fn at_tick(&self, tick: u64) -> Option<&GameStateSnapshot>

Find the snapshot with the given tick, or the nearest one before it.

pub fn bracket( &self, tick: u64, ) -> Option<(&GameStateSnapshot, &GameStateSnapshot)>

Find the two snapshots that bracket tick for interpolation. Returns (older, newer).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn clear(&mut self)
