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
