What Are the Most Important Standard Library Traits in Rust?

The most important standard library traits in Rust are Debug, PartialEq, Clone, Copy, PartialOrd, and Ord, which enable printing, comparison, and duplication of types.

#[derive(Debug, PartialEq, Clone, Copy, PartialOrd, Ord)]
struct ShirtColor {
    red: bool,
}

These traits are automatically implemented using the #[derive(...)] attribute, allowing you to use operators like ==, <, and println! without manual implementation.

These traits are like built-in capabilities you can give to your custom data types so they can be printed, compared, or copied easily. Think of them as adding standard features to a product so it works with all the tools in your workshop without needing custom adapters.
