error[E0005]: refutable pattern in function argument: `(_, _)` not covered
--> $DIR/refutable-pattern-errors.rs:3:9
|
LL | fn func((1, (Some(1), 2..=3)): (isize, (Option<isize>, isize))) { }
| ^^^^^^^^^^^^^^^^^^^^^ pattern `(_, _)` not covered
error[E0005]: refutable pattern in local binding: `(std::i32::MIN..=0i32, _)` and `(2i32..=std::i32::MAX, _)` not covered
--> $DIR/refutable-pattern-errors.rs:7:9
|
LL | let (1, (Some(1), 2..=3)) = (1, (None, 2));
| ^^^^^^^^^^^^^^^^^^^^^ patterns `(std::i32::MIN..=0i32, _)` and `(2i32..=std::i32::MAX, _)` not covered
|
= note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant
= note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html
help: you might want to use `if let` to ignore the variant that isn't matched
