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();
   |                               ++++++++

UI Tests

This folder contains rustc's UI tests.

Test Directives (Headers)

Typically, a UI test will have some test directives / headers which are special comments that tell compiletest how to build and intepret a test.

As part of an on-going effort to rewrite compiletest (see https://github.com/rust-lang/compiler-team/issues/536), a major change proposal to change legacy compiletest-style headers // <directive> to ui_test-style headers //@ <directive> was accepted (see https://github.com/rust-lang/compiler-team/issues/512.

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>.
