Static rustc_lint_defs::builtin::UNUSED_MACROS
source · 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.
