error: irrefutable `if let` pattern
--> $DIR/deny-irrefutable-let-patterns.rs:6:8
|
LL | if let _ = 5 {}
| ^^^^^^^^^
|
= note: this pattern will always match, so the `if let` is useless
= help: consider replacing the `if let` with a `let`
note: the lint level is defined here
--> $DIR/deny-irrefutable-let-patterns.rs:3:9

LL | #![deny(irrefutable_let_patterns)]
| ^^^^^^^^^^^^^^^^^^^^^^^^
error: irrefutable `while let` pattern
--> $DIR/deny-irrefutable-let-patterns.rs:8:11
|
LL | while let _ = 5 {
| ^^^^^^^^^
|
= note: this pattern will always match, so the loop will never exit
= help: consider instead using a `loop { ... }` with a `let` inside it
error: irrefutable `if let` guard pattern
--> $DIR/deny-irrefutable-let-patterns.rs:13:14
|
LL | _ if let _ = 2 => {}
| ^^^^^^^^^
|
= note: this pattern will always match, so the guard is useless
= help: consider removing the guard and adding a `let` inside the match arm
error: aborting due to 3 previous errors
