Rustint

Rustint is a Rust library for working with RGB colors. It provides a simple and efficient way to create, manipulate, and convert colors in Rust applications.

Features

Create RGB colors
Interpolate between two colors
Convert hexadecimal color strings to RGB
Convert RGB colors to hexadecimal strings
Error handling for invalid color formats

Installation

Add this to your Cargo.toml:

[dependencies]
rustint = "0.1.0"

Usage

Creating a Color

use rustint::Color;

let red = Color::new(255, 0, 0);
let blue = Color::new(0, 0, 255);

// or

let red = Color::try_from("#FF0000").unwrap();
let blue = Color::try_from("#0000FF").unwrap();

Interpolating Between Colors

let red = Color::new(255, 0, 0);
let blue = Color::new(0, 0, 255);
let purple = red.interpolate(&blue, 50.0);
println!("Purple: {}", purple); // Outputs: Purple: #7F007F

Converting to Hex String

let color = Color::new(128, 64, 32);
println!("Hex: {}", color); // Outputs: Hex: #804020

Error Handling

The library provides custom error types for handling invalid color formats:

use rustint::{Color, ColorError};

let result = Color::try_from("#INVALID");
match result {
    Ok(color) => println!("Valid color: {}", color),
    Err(ColorError::InvalidFormat) => println!("Invalid format"),
    Err(ColorError::InvalidHexValue) => println!("Invalid hex value"),
}
