error[E0004]: non-exhaustive patterns: `Foo(_, _)` not covered
--> $DIR/tuple-struct-nonexhaustive.rs:5:11
|
LL | match x {
| ^ pattern `Foo(_, _)` not covered
|
note: `Foo` defined here
--> $DIR/tuple-struct-nonexhaustive.rs:1:8
|
LL | struct Foo(isize, isize);
| ^^^
= note: the matched value is of type `Foo`
= note: `isize` does not have a fixed maximum value, so a wildcard `_` is necessary to match exhaustively
= help: add `#![feature(precise_pointer_size_matching)]` to the crate attributes to enable precise `isize` matching
help: ensure that all possible cases are being handled by adding a match arm with a wildcard pattern or an explicit pattern as shown

LL ~ Foo(2, b) => println!("{}", b),
LL + Foo(_, _) => todo!()
