+//! 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.
