warning: creating a mutable reference to mutable static is discouraged

LL | S1 { a: unsafe { &mut X1 } }
|
|
| ^^^^^^^ 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 | S1 { a: unsafe { addr_of_mut!(X1) } }
