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
