warning: creating a mutable reference to mutable static is discouraged

--> $DIR/borrowck-unsafe-static-mutable-borrows.rs:19:30
|

|
LL | let sfoo: *mut Foo = &mut SFOO;
|
|
| ^^^^^^^^^ mutable 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 mutable reference has lifetime `'static`, but if the static gets accessed (read or written) by any other means, or any other reference is created, then any further use of this mutable reference is Undefined Behavior
|
|
= note: `#[warn(static_mut_refs)]` on by default
|
|
help: use `addr_of_mut!` instead to create a raw pointer
|
|
|
|
|
LL | let sfoo: *mut Foo = addr_of_mut!(SFOO);
