Generate a random rgba()-formatted color.
Inspired by "random-rgb-color" by mrmrs, which was in turn inspired by random-hex-color by John Otander.
This is a simple project for learning idiomatic Rust, publishing Rust projects, and how to approximate other programs using Rust.
It can be used to generate a string such as rgba(179, 134, 103, 0.33), or a rust struct that looks like this:
rust
RandomColor {
red: 189,
green: 138,
blue: 54,
alpha: 0.79
}
