--> $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

= note: for more information, see <https://doc.rust-lang.org/nightly/edition-guide/rust-2021/disjoint-capture-in-closures.html>

LL | #![deny(rust_2021_incompatible_closure_captures)]

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

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