AssetClosureStore

Struct AssetClosureStore 

Source
pub struct AssetClosureStore {
    pub slots: Vec<Option<Closure<dyn FnMut()>>>,
    pub settled: Vec<bool>,
}
Expand description

The backing store behind AssetClosures.

Slots are appended in pairs by AssetLoader::load_image — even indices hold an onload closure, odd indices the matching onerror closure — so a callback can identify its own slot with one captured index.

The fields are public because the type is reachable from the public AssetClosures alias: a private-field type exposed through a public alias would be unusable to callers, and the retained-slot count is genuinely useful as a leak diagnostic.

Fields§

§slots: Vec<Option<Closure<dyn FnMut()>>>

The load callbacks, in registration order. A None slot is one that has already been released by AssetLoader::collect.

§settled: Vec<bool>

Whether the closure in the slot at the same index has run. A settled closure cannot free itself (see AssetClosures) but is no longer keeping anything alive that the cache still needs.
