impl CachedRenderingData

pub fn release<T>(&self, cache: &mut RenderingCache<T>) -> Option<T>

This function can be used to remove an entry from the rendering cache for a given item, if it exists, i.e. if any data was ever cached. This is typically called by the graphics backend’s implementation of the release_item_graphics_cache function.

    &self,
    cache: &'a mut RenderingCache<T>
) -> Option<&'a mut CachedGraphicsData<T>>

Return the value if it is in the cache
