struct KeyCache {
cache: KeyCacheState,
images_pending_keys: VecDeque<PendingKey>,
}Expand description
As getting new keys takes a round trip over the constellation, we keep a small cache of them. Additionally, this cache will store image resources that do not have a key yet because those are needed to complete the load.
Fields§
§cache: KeyCacheStateA cache of WebRenderImageKey.
images_pending_keys: VecDeque<PendingKey>These images are loaded but have no key assigned to yet.
