Struct CacheHints 

#[non_exhaustive]
pub struct CacheHints {
    pub scene_generation: u64,
    pub selection_generation: u64,
}

Renderer invalidation hints for one frame.

Generation counters let the renderer skip batch rebuild and GPU upload when neither scene content nor selection has changed since the previous frame.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

scene_generation: u64

Scene version counter from Scene::version(). Default: 0 (triggers rebuild on first frame).

selection_generation: u64

Selection version counter from Selection::version(). Default: 0.
