Struct Held 

Source 
struct Held {
    element: HtmlImageElement,
    url: String,
    load: Rc<Cell<Load>>,
    _handlers: [Closure<dyn FnMut()>; 2],
}
Expand description

One registered asset: the element the browser decodes into, the object URL backing it, and how far it has got.

Fields§

§element: HtmlImageElement§url: String§load: Rc<Cell<Load>>§_handlers: [Closure<dyn FnMut()>; 2]

The handlers that move load along, kept alive for as long as the element they are bound to.
