How does trait inheritance work

Rust does not support trait inheritance; instead, it uses trait objects and default implementations to share behavior. You define a trait with shared methods and implement it on multiple structs, optionally providing default logic in the trait itself.

trait Draw {
    fn draw(&self) {
        println!("Drawing default shape");
    }
}

struct Button;
impl Draw for Button {}

struct Image;
impl Draw for Image {
    fn draw(&self) {
        println!("Drawing image");
    }
}

Rust doesn't let one type inherit code from another like in other languages. Instead, you define a shared contract called a trait that multiple types can agree to follow. Think of it like a job description: different employees (types) can do the same job (trait) in their own way, or use the standard instructions provided by default.
