| error: captured variable cannot escape `FnMut` closure body |
| --> $DIR/issue-69446-fnmut-capture.rs:19:17 |
| | |
| LL | let mut x = Foo; |
| | ----- variable defined here |
| LL | bar(move || async { |
| | _______________-_^ |
| | | | |
| | | inferred to be a `FnMut` closure |
| LL | | x.foo(); |
| | | - variable captured here |
| LL | | }); |
| | |_____^ returns an `async` block that contains a reference to a captured variable, which then escapes the closure body |
| | |
| = note: `FnMut` closures only have access to their captured variables while they are executing... |
| = note: ...therefore, they cannot allow references to captured variables to escape |
