Struct DeltaSnapshot 

pub struct DeltaSnapshot {
    pub tick: u64,
    pub timestamp: f64,
    pub base_tick: u64,
    pub changed: Vec<EntityDelta>,
}

Compact diff between two GameStateSnapshot values.

Only entities that changed are included. The receiver applies the delta on top of the last ack’d base snapshot to reconstruct the new state.

Fields

tick: u64

Tick this delta advances the client to.

timestamp: f64

base_tick: u64

Which base tick this delta is relative to (last ack’d by client).

changed: Vec<EntityDelta>

Implementations

impl DeltaSnapshot

pub fn new(tick: u64, timestamp: f64, base_tick: u64) -> Self

pub fn build(base: &GameStateSnapshot, current: &GameStateSnapshot) -> Self

Build a DeltaSnapshot by diffing base → current.

pub fn apply(&self, base: &GameStateSnapshot) -> GameStateSnapshot

Apply this delta on top of base, producing a new full snapshot.

pub fn change_count(&self) -> usize

Count of entities affected by this delta.
