jsCast | : radio : An Audio Streaming Application written in JavaScript | Audio Utils library

This construction:

Although Rust arrays and slices have an into_iter method it returns the same Iterator as the iter method does which iterates over references to values instead of the values themselves. Yes, this is confusing. Since JsValue::from is implemented for u32 but not for &u32 you can take your Iterator and convert it to a Iterator using the copied method. Fixed working examples:

First, you are trying to copy name into a number of instances of File, but it must be cloned. Second, you need to properly ensure that all_files will be available whenever a closure wants to call it. One way to do so is by using a RefCell to enable multiple closures to write to it, and wrapping that in a Rc to ensure that it stays alive as long as any of the closures are alive.

Try this:

The wasm_bindgen::JsCast::dyn_into documentations states it relies on JsCast::has_type, which in turn calls JsCast::instanceof. And indeed web_sys::Element does implement JsCast trait. So do the other HTML element types such as HtmlButtonElement.

The implementation is generated from Web IDL files, which are the formal definition of web browser interfaces. However:
