I have variable x = JsValue(MIDIAccess). How do I get to the MIDIAccess object? I tried x.0 but get an error stating the field is undefined.
Thanks,

From the names of your types, I presume you're using web_sys
and wasm_bindgen
.
JsValue
isn't a tuple, so .0
will not work. The JsCast
trait can be used to cast between JS types:
use wasm_bindgen::JsCast;
let midi: Result<MIDIAccess, JsValue> = x.dyn_into();
You can also use the standard From
and Into
traits, but I think they'll panic if you mix up your types.
Thank you, I got it working!
