Static UNUSED_IMPORT_BRACES 

static UNUSED_IMPORT_BRACES: &Lint

The unused_import_braces lint catches unnecessary braces around an imported item.

Example

#![deny(unused_import_braces)]
use test::{A};

pub mod test {
    pub struct A;
}

{{produces}}

Explanation

If there is only a single item, then remove the braces (use test::A; for example).

This lint is “allow” by default because it is only enforcing a stylistic choice.
