error[E0005]: refutable pattern in local binding
|
|
--> $DIR/exhaustive_patterns.rs:20:9
|
|
|
|
|
LL | let Either::A(()) = foo();
|
|
| ^^^^^^^^^^^^^ pattern `Either::B(_)` 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: `Either<(), !>` defined here
|
|
--> $DIR/exhaustive_patterns.rs:10:6
|
|
|
|
|
LL | enum Either<A, B> {
|
|
| ^^^^^^
|
|
LL | A(A),
|
|
LL | B(inner::Wrapper<B>),
|
|
| - not covered
|
|
= note: pattern `Either::B(_)` is currently uninhabited, but this variant contains private fields which may become inhabited in the future
|
|
= note: the matched value is of type `Either<(), !>`
|
|
help: you might want to use `if let` to ignore the variant that isn't matched
|
|
|
|
|
LL | if let Either::A(()) = foo() { todo!() };
