| error[E0015]: cannot call non-const function `format` in statics | 
 |   --> $DIR/issue-64453.rs:4:31 | 
 |    | | 
 | LL | static settings_dir: String = format!(""); | 
 |    |                               ^^^^^^^^^^^ | 
 |    | | 
 | note: function `format` is not const | 
 |   --> $SRC_DIR/alloc/src/fmt.rs:LL:COL | 
 |    = note: calls in statics are limited to constant functions, tuple structs and tuple variants | 
 |    = note: consider wrapping this expression in `std::sync::LazyLock::new(|| ...)` | 
 |    = note: this error originates in the macro `format` (in Nightly builds, run with -Z macro-backtrace for more info) |

 | error[E0507]: cannot move out of static item `settings_dir` | 
 |   --> $DIR/issue-64453.rs:13:37 | 
 |    | | 
 | LL |     let settings_data = from_string(settings_dir); | 
 |    |                                     ^^^^^^^^^^^^ move occurs because `settings_dir` has type `String`, which does not implement the `Copy` trait | 
 |    | | 
 | help: consider cloning the value if the performance cost is acceptable | 
 |    | | 
 | LL |     let settings_data = from_string(settings_dir.clone()); |
