説明
wasm_bindgen is a little bit different than the issue that's been resolved with traits. In particular, wasm_bindgen just generates code around the non-trait implemented function, and the only way to use native JS arrays as parameters is to use Box<[...]>.
In general, I think maybe boxed slices should be considered ok for local parameters, as they're conceptually very similar to vectors.
