error[E0507]: cannot move out of `val`, a captured variable in an `FnMut` closure
--> $DIR/issue-87456-point-to-closure.rs:10:28
|
LL | let val = String::new();
| --- captured outer variable
LL |
LL | take_mut(|| {
| -- captured by this `FnMut` closure
LL |
LL | let _foo: String = val;
| ^^^ move occurs because `val` has type `String`, which does not implement the `Copy` trait
|
help: consider borrowing here
|
LL | let _foo: String = &val;
| +
help: consider cloning the value if the performance cost is acceptable
|
LL | let _foo: String = val.clone();

An example directive is ignore-test. In legacy compiletest style, the header
would be written as
// ignore-test
but in ui_test style, the header would be written as
//@ ignore-test
compiletest is changed to accept only //@ directives for UI tests
(currently), and will reject and report an error if it encounters any
comments // <content> that may be parsed as an legacy compiletest-style
test header. To fix this, you should migrate to the ui_test-style header
//@ <content>.
