Struct SceneSnapshot 

pub struct SceneSnapshot {
    pub next_grid_id: u32,
    pub grids: Vec<(GridId, GridSnapshot)>,
}

Top-level scene snapshot — full state needed to reconstruct a Scene via Scene::from_snapshot.

Grids serialised as a Vec<(GridId, GridSnapshot)> rather than a HashMap so the wire form is independent of HashMap’s non-deterministic iteration order — the same scene snapshot twice in a row produces byte-identical output.

Fields

next_grid_id: u32

Next id Scene::add_grid will hand out. Preserved across snapshot round-trips so removed-id non-reuse holds.

grids: Vec<(GridId, GridSnapshot)>

All registered grids paired with their ids.
