warning: creating a mutable reference to mutable static is discouraged
--> src/main.rs:217:73
|
217 | pub fn get_input() -> &'static mut FastInput { unsafe { &mut INPUT } }
| ^^^^^^^^^^ 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
