error[E0005]: refutable pattern in local binding: `Foo::A(_)` not covered
--> $DIR/uninhabited-irrefutable.rs:27:9
|
LL | let Foo::D(_y, _z) = x;
| ^^^^^^^^^^^^^^ pattern `Foo::A(_)` 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: `Foo` defined here
--> $DIR/uninhabited-irrefutable.rs:19:5
|
LL | enum Foo {
| ---
LL | A(foo::SecretlyEmpty),
| ^ not covered
= note: the matched value is of type `Foo`
help: you might want to use `if let` to ignore the variant that isn't matched
|
LL | let (_y, _z) = if let Foo::D(_y, _z) = x { (_y, _z) } else { todo!() };
| +++++++++++++++++ +++++++++++++++++++++++++++++
help: alternatively, you might want to use let else to handle the variant that isn't matched
|
LL | let Foo::D(_y, _z) = x else { todo!() };
| ++++++++++++++++
