    pub static UNUSED_MACROS: &Lint

Expand description

The `unused_macros` lint detects macros that were not used.

Note that this lint is distinct from the `unused_macro_rules` lint, which checks for single rules that never match of an otherwise used macro, and thus never expand.

#### §Example

    macro_rules! unused {
        () => {};
    }

    fn main() {
    }

{{produces}}

#### §Explanation

Unused macros may signal a mistake or unfinished code. To silence the warning for the individual macro, prefix the name with an underscore such as `_my_macro`. If you intended to export the macro to make it available outside of the crate, use the `macro_export` attribute.
