Crate trace4rs

This crate allows users to configure output from tracing in the same way as you would configure the output of log4rs.

Overview

For a usage example see the examples folder or src/test.rs.

Benchmarks & Results

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. See for yourself with cargo bench --features tracing-macros
