Tip: In she'll context, it is good style to always print argv[0] in log lines, ie the program name. When myscript.rs reports

    INFO: blabla
It should better report

    myscript.rs: blabla
    or myscript.rs: INFO: blabla
This helps identifying the source when the script is part of a series of pipes, or running in background, etc

This is such a good idea. When shell scripts are all written in Rust, Unix will be a safe and secure operating system.
