A logging facade provides a single logging API that abstracts over the actual logging implementation. Libraries can use the logging API provided by this crate, and the consumer of those libraries can choose the logging implementation that is most suitable for its use case. Sources
As a backend facility, we will use the simple_logger crate. This crate will simply output messages formatted like this 2015-02-24 01:05:20 WARN [logging_example] This is an example message.
