warning: creating a shared reference to mutable static is discouraged
|
|
--> $DIR/issue-23338-ensure-param-drop-order.rs:93:31
|
|
|
|
|
LL | (mem::size_of_val(&trails) * 8) as u32
|
|
| ^^^^^^^ 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
|
