//! # rust-colors
//! `rust-colors` is a library for parsing ANSI Strings to colors.
//!
//! ## Example
//! ```rust
//! use rust_colors::{Ansi, Color, Colors};
//!
//! fn my_function() {
//!     let colors = Ansi;
//!    
//!     println!(
//!         "The sky is {}, apples can be {}, do you like to touch {} grass?",
//!         colors.color("blue", Colors::Blue),
//!         colors.bold_color("red", Colors::Red),
//!         colors.underline_color("green", Colors::Green),
//!     );
//! }
//!
//! ```
