Static rustc_lint_defs::builtin::DEAD_CODE

pub static DEAD_CODE: &Lint

The dead_code lint detects unused, unexported items.

Example

fn foo() {}

{{produces}}

Explanation

Dead code may signal a mistake or unfinished code. To silence the warning for individual items, prefix the name with an underscore such as _foo. If it was intended to expose the item outside of the crate, consider adding a visibility modifier like pub.

To preserve the numbering of tuple structs with unused fields, change the unused fields to have unit type or use PhantomData.

Otherwise consider removing the unused code.
