= 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
