1///
2/// This enum is a replica of the Level and LevelFilter
3/// enums from the log crate : https://crates.io/crates/log
4///
5/// The original references can be found here:
6/// - https://docs.rs/log/latest/log/enum.Level.html
7/// - https://docs.rs/log/latest/log/enum.LevelFilter.html
8///
9/// This is embedded directly into this crate to to allow
10/// usage of log levels while retaining the ability to embed
11/// the log crate itself as an optional feature. This is done
12/// to accomodate reduced bytecode requirements of build
13/// targets such as BPF.
