method / constant was impl on primitive type

[MahadMuhammad]

Compilation Successful when method / constant was impl on primitive type E0390

• Fixing this issue, will also help gccrs to emit error codes similiar to rustc.
• You can view the same on compiler-explorer

---

I tried this code from E0390:

#![allow(unused)]
fn main() {
struct Foo {
    x: i32
}

impl *mut Foo {}
// error: cannot define inherent `impl` for primitive types
}

---

I expected to see this happen:

• Give error like rustc, i.e.,

error[E0390]: only a single inherent implementation marked with `#[lang = "mut_ptr"]` is allowed for the `*mut T` primitive

---

Instead, this happened:

• Compiled Successfully.

Compiler returned: 0

Hey, I'm new here and I'd like to get involved with gccrs, could someone assign me this issue?

there you go @ericwu17, thanks a lot!!! feel free to ask any questions you have here or on our Zulip https://gcc-rust.zulipchat.com/

Hi @CohenArthur, thanks for assigning me this issue. However, I got caught up in other things that have taken priority over gccrs, so I won't be making contributions here in the near future. I'm still interested and maybe I'll look into this issue later, but for now I've unassigned myself.

Best wishes :)

that's no problem @ericwu17!! thanks for letting us know :D best of luck in your endeavors!!
