Topic: WIT: Failable constructor?

Hey, I'm pretty new to wasip2 and WIT.
Trying to create a WIT file for Rust library.
The problem is that failable constructor doesn't work with wit-bindgen:

resource mystruct {
    constructor(a: u32) -> result<mystruct, my-error>;
}

Any standard way to express it in WIT?

Another one: option<T> is not allowed in constructors?
