pub enum TextureCacheHandle {
    Empty,
    Auto(WeakFreeListHandle<AutoCacheEntryMarker>),
    Manual(WeakFreeListHandle<ManualCacheEntryMarker>),
}
Expand description

A texture cache handle is a weak reference to a cache entry.

If the handle has not been inserted into the cache yet, or if the entry was previously inserted and then evicted, lookup of the handle will fail, and the cache handle needs to re-upload this item to the texture cache (see request() below).

Variants§

§

Empty

A fresh handle.

§

Auto(WeakFreeListHandle<AutoCacheEntryMarker>)

A handle for an entry with automatic eviction.

§

Manual(WeakFreeListHandle<ManualCacheEntryMarker>)

A handle for an entry with manual eviction.
