1 error: captured variable cannot escape `FnMut` closure body
2 --> $DIR/issue-69446-fnmut-capture.rs:19:17
5 | ----- variable defined here
6 LL | bar(move || async {
9 | | inferred to be a `FnMut` closure
11 | | - variable captured here
13 | |_____^ returns an `async` block that contains a reference to a captured variable, which then escapes the closure body
15 = note: `FnMut` closures only have access to their captured variables while they are executing...
16 = note: ...therefore, they cannot allow references to captured variables to escape
17 = note: requirement occurs because of a mutable reference to `Context<'_>`
18 = note: mutable references are invariant over their type parameter
19 = help: see <https://doc.rust-lang.org/nomicon/subtyping.html> for more information about variance
