error: changes to closure capture in Rust 2021 will affect drop order
|
|
--> $DIR/macro.rs:19:13
|
|

LL | let _ = || dbg!(a.0);
|
|
| ^^ --- in Rust 2018, this closure captures all of `a`, but in Rust 2021, it will only capture `a.0`
|
|
...
|
|
LL | }
|
|
| - in Rust 2018, `a` is dropped here, but in Rust 2021, only `a.0` will be dropped here as part of the closure

help: add a dummy let to cause `a` to be fully captured

LL | let _ = || { let _ = &a; dbg!(a.0) };
