| error[E0005]: refutable pattern in local binding |

| | ^^^^^^^^^^^^^^^^^^^^^ patterns `(i32::MIN..=0_i32, _)` and `(2_i32..=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 |
| = note: the matched value is of type `(i32, (Option<i32>, i32))` |
| help: you might want to use `if let` to ignore the variants that aren't matched |
