| | ^^^^^^^^^^^^ pattern `T(_, _)` 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 `Helper<T, U>` |
| help: you might want to use `if let` to ignore the variant that isn't matched |

| LL | if let Helper::U(u) = Helper::T(t, []) { /* */ } |
