-//! Log traits live here, which are called throughout the library to provide useful information for
-//! debugging purposes.
-//!
-//! There is currently 2 ways to filter log messages. First one, by using compilation features, e.g "max_level_off".
-//! The second one, client-side by implementing check against Record Level field.
-//! Each module may have its own Logger or share one.
