Struct egui::util::cache::FrameCache

source ·
pub struct FrameCache<Value, Computer> { /* private fields */ }
Expand description

Caches the results of a computation for one frame. If it is still used next frame, it is not recomputed. If it is not used next frame, it is evicted from the cache to save memory.

Implementations§
