warning: creating a shared reference to mutable static is discouraged
|
|
--> $DIR/static-recursive.rs:3:36
|
|
|
|
|
LL | static mut S: *const u8 = unsafe { &S as *const *const u8 as *const u8 };
|
|
| ^^ shared reference to mutable static
|
|
|
|
|
= note: for more information, see issue #114447 <https://github.com/rust-lang/rust/issues/114447>
|
|
= note: this will be a hard error in the 2024 edition
|
|
= note: this shared reference has lifetime `'static`, but if the static ever gets mutated, or a mutable reference is created, then any further use of this shared reference is Undefined Behavior
|
|
= note: `#[warn(static_mut_refs)]` on by default
|
|
help: use `addr_of!` instead to create a raw pointer
|
|

|
LL | static mut S: *const u8 = unsafe { addr_of!(S) as *const *const u8 as *const u8 };
