error: captured variable cannot escape `FnMut` closure body
|
|
--> $DIR/issue-53040.rs:3:8
|
|
|
|
|
LL | let mut v: Vec<()> = Vec::new();
|
|
| ----- variable defined here
|
|
LL | || &mut v;
|
|
| - ^^^^^-
|
|
| | | |
|
|
| | | variable captured here
|
|
| | returns a reference to a captured variable which escapes the closure body
|
|
| inferred to be a `FnMut` closure
|
|
|
|
|
= 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
