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

source

impl<Value, Computer> FrameCache<Value, Computer>

source

pub fn new(computer: Computer) -> Self

source

pub fn evice_cache(&mut self)

Must be called once per frame to clear the cache.

source

impl<Value, Computer> FrameCache<Value, Computer>

source

pub fn get<Key>(&mut self, key: Key) -> Value where
 Key: Copy + Hash,
 Value: Clone,
 Computer: ComputerMut<Key, Value>,

Get from cache (if the same key was used last frame) or recompute and store in the cache.
