error[E0005]: refutable pattern in local binding
|
|
--> $DIR/empty-never-array.rs:10:9
|
|
|
|
|
LL | let Helper::U(u) = Helper::T(t, []);
|
|
| ^^^^^^^^^^^^ pattern `Helper::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: `Helper<T, U>` defined here
|
|
--> $DIR/empty-never-array.rs:3:6
|
|
|
|
|
LL | enum Helper<T, U> {
|
|
| ^^^^^^
|
|
LL | T(T, [!; 0]),
|
|
| - not covered
|
|
= note: the matched value is of type `Helper<T, U>`
|
|
help: you might want to use `let else` to handle the variant that isn't matched
|
|
|
|
|
LL | let Helper::U(u) = Helper::T(t, []) else { todo!() };
