# flnm - Breaks apart a file's path by "/" and returns only the number of folder specified for each side,
#        followed by the file name.
#
# usage: flnm <filename> <leading elements> <trailing elements>
#        if <leading elements> is provided and <trailing elements> is omitted, then returns ONLY the back n portions
#        if <leading elements> is provided and <trailing elements> is omitted, then returns ONLY the file nane
#        if <leading elements> + <trailing elements> exceeds the file's actual path length, then returns full file path
#        if both <leading elements> and <trailing elements> are omitted, it assumes a value of 1 for each

//! TOML Value Manipulation Demonstration
//!
//! This code is to supplement this excellent article:

//!     [Rust: Read, Write, and Modify .toml Files — Another way to handle User Set Environment Variables](https://medium.com/@itsuki.enjoy/rust-read-write-and-modify-toml-files-another-way-to-handle-user-set-environment-variables-27e1baf1a65f)
//!
//! This demo code assumes you have added additional entries to your ~/.cargo/config.toml file. Although, I used 
//! `foo` and `bar` instead of the `password` and `username` that the article uses.
//!
//! Put this code into `main.rs`. And, here is the corresponding `Cargo.toml` needed for this demo.
