error: irrefutable `if let` guard pattern
--> $DIR/warns.rs:6:20
|
LL | Some(x) if let () = x => {}
| ^^^^^^^^^^
|
= note: this pattern will always match, so the guard is useless
= help: consider removing the guard and adding a `let` inside the match arm
note: the lint level is defined here
--> $DIR/warns.rs:3:8
|
LL | #[deny(irrefutable_let_patterns)]
| ^^^^^^^^^^^^^^^^^^^^^^^^
error: unreachable pattern
