Hello, I don't understand why the following global `static` declaration is error even I don;t have any multi-thread code? Thank you. use std::cell::OnceCell; #[derive(Debug)] struct Config { database_url: String, feature_flags: Vec<String>, } static CONFIG: OnceCell<Config> = OnceCell::new(); fn main() { ..... } The error is as below although no multi-thread codes and I want to use `OnceCell` for a lazy init: 10 | static CONFIG: OnceCell<Config> = OnceCell::new(); | ^^^^^^^^^^^^^^^^^^^ `OnceCell<Config>` cannot be shared between threads safely | = help: the trait `Sync` is not implemented for `OnceCell<Config>` = note: if you want to do aliasing and mutation between multiple threads, use `std::sync::OnceLock` instead = note: shared static variables must have a type that implements `Sync`

This PR adds the FeatureFlag suffix to the feature flag types that were missing them. This makes the names easier to search in the codebase. Release Notes: N/A
