1 error[E0005]: refutable pattern in local binding: `Foo::A(_)` not covered
2 --> $DIR/uninhabited-irrefutable.rs:27:9
4 LL | let Foo::D(_y, _z) = x;
5 | ^^^^^^^^^^^^^^ pattern `Foo::A(_)` not covered
7 = note: `let` bindings require an "irrefutable pattern", like a `struct` or an `enum` with only one variant
8 = note: for more information, visit https://doc.rust-lang.org/book/ch18-02-refutability.html
9 note: `Foo` defined here
10 --> $DIR/uninhabited-irrefutable.rs:19:5
14 LL | A(foo::SecretlyEmpty),
16 = note: the matched value is of type `Foo`
17 help: you might want to use `if let` to ignore the variant that isn't matched
19 LL | let (_y, _z) = if let Foo::D(_y, _z) = x { (_y, _z) } else { todo!() };
20 | +++++++++++++++++ +++++++++++++++++++++++++++++
21 help: alternatively, on nightly, you might want to use `#![feature(let_else)]` to handle the variant that isn't matched
23 LL | let Foo::D(_y, _z) = x else { todo!() };
