|
= note: reference of mutable static is a hard error from 2024 edition
|
||
|
|
= note: mutable statics can be written to by multiple threads: aliasing violations or data races will cause undefined behavior
|
||
|
|
= note: `#[warn(static_mut_ref)]` on by default
|
||
|
|
help: mutable references are dangerous since if there's any other pointer or reference used for that static while the reference lives, that's UB; use `addr_of_mut!` instead to create a raw pointer
