Static AMBIGUOUS_GLOB_IMPORTS

pub static AMBIGUOUS_GLOB_IMPORTS: &'static Lint

The ambiguous_glob_imports lint detects glob imports that should report ambiguity errors, but previously didn’t do that due to rustc bugs.

Example

#![deny(ambiguous_glob_imports)]
pub fn foo() -> u32 {
    use sub::*;
    C
}

mod sub {
    mod mod1 { pub const C: u32 = 1; }
    mod mod2 { pub const C: u32 = 2; }

    pub use mod1::*;
    pub use mod2::*;
}

{{produces}}

Explanation

Previous versions of Rust compile it successfully because it had lost the ambiguity error when resolve use sub::mod2::*.

This is a future-incompatible lint to transition this to a hard error in the future.
