Is it possible to mark a C++ type as `Trivial`? about cxx

[dtolnay]

Yep, something like this should work:

#[cxx::bridge]
mod ffi {
    unsafe extern "C++" {
        include!("example/include/metasim.h");

        type Type = crate::Type;
        fn metasim() -> Type;
    }
}

#[derive(Debug)]
#[repr(transparent)]
pub struct Type(std::ffi::c_int);

unsafe impl cxx::ExternType for Type {
    type Kind = cxx::kind::Trivial;
    type Id = cxx::type_id!("Type");
}

fn main() {
    println!("{:?}", ffi::metasim());
}

Wow! Perfect... and simple! Thank you 🙏
