CLI - Command Line Interface in Rust

Rust provides access to the values on the command line via the std::env::args function. We can use this in its raw form:

• ARGV - command line parameters for simple CLI program
• Expect one command line parameter in Rust

There are also crates that provide a much nicer and more comprehensive interface to parse the content of args that were provided on the command line. We cover:

• Clap - Command Line Argument Parser for Rust

We also maintain a list of Open Source Applications with links to many command line applications written in Rust.
