- Remove `expect` in favor of `unwrap` when the `Result`'s error variant contains the info in the `expect` anyway (eg. when locking things). The line number/context are given by the backtrace. - Remove over-specification of types (`&T` instead of `&RWReadLockGuard`) - Put reused values into constants - `FromStr` instead of manual function - Change `if let Some(()) = ...` to `if T.is_some()`
