#[derive(Reflect)] compile error when std::fmt::Result is imported

[Seldom-SE]

Bevy version

0.9.1

What you did

For example,

use std::fmt::{Debug, Formatter, Result};

use bevy::prelude::*;

fn main() {}

#[derive(Reflect)]
struct MyStruct;

struct MyError;

impl Debug for MyError {
    fn fmt(&self, f: &mut Formatter<'_>) -> Result {
        write!(f, "something occured")
    }
}

What went wrong

I get this error:

error[E0107]: this type alias takes 0 generic arguments but 2 generic arguments were supplied
  --> src/main.rs:7:10

7  | #[derive(Reflect)]
   |          ^^^^^^^- help: remove these generics

   |          ^^^^^^
   = note: this error originates in the derive macro `Reflect` (in Nightly builds, run with -Z macro-backtrace for more info)

Additional information

Looks like #[derive(Reflect)] uses Result instead of ::core::result::Result. I looked into it, but I couldn't find how this was occurring haha.

Thanks!

Duplicate of #3004.

This should be fixed in main and the soon-to-be-released 0.10 version! 😄

Ah, nice
