This crate allows users to configure output from
tracing in the same way as you would configure the
output of log4rs.
For a usage example see the examples folder or src/test.rs.
The takeaway is that the actual appenders are roughly equivalent in
performance. However, when using the tracing macros vs the log macros
the appender performance is roughly 2 orders of magnitude larger.
