//! Regression test for `#[derive(Debug)]` on enums with uninhabited variants.
//!
//! Ensures there are no special warnings about uninhabited types when deriving
//! Debug on an enum with uninhabited variants, only standard unused warnings.
//!
//! Issue: https://github.com/rust-lang/rust/issues/38885
//@ check-pass
//@ compile-flags: -Wunused
#[derive(Debug)]
enum Void {}
#[derive(Debug)]
enum Foo {
Bar(#[allow(dead_code)] u8),
Void(Void), //~ WARN variant `Void` is never constructed
}
fn main() {
let x = Foo::Bar(42);
println!("{:?}", x);
