Description
The macro reference should explain how #[cfg] and #[cfg_attr(...)] behave inside macros.
Does this macro check the allow_clippy flag of the crate the macro is defined in, or of the crate the macro is used in?
macro_rules! field_check {
($type:path, $field:tt) => {
// Make sure the field actually exists. This line ensures that a
// compile-time error is generated if $field is accessed through a
// Deref impl.
#[cfg_attr(allow_clippy, allow(clippy::unneeded_field_pattern))]
let $type { $field: _, .. };
};
}
