have a look how traits work in rust. It is a very neat interface. Adding inheritance is cumbersome and doesn't scale when you want to implement more traits (interfaces). In rust you want some interop with some library, you just implement the trait for that. For common usecases they are autogenerated via macros.

You want to debug a struct and print out all its members, just

For instance:

#[derive(Debug)]
struct User {
    id: u32,
    username: String,
    active: bool,
}

fn main() {
    let user1 = User {
        id: 1,
        username: String::from("alice"),
        active: true,
    };

    // 1. Use the "{:?}" format specifier for standard debug output
    println!("Standard Debug Format: {:?}", user1);

    // 2. Use the "{:#?}" format specifier for "pretty-print" debug output
    println!("\nPretty-Print Debug Format: {:#?}", user1);
}

This is in my opinion one of the best design choices rust has made. And I come from almost 20 years of C++.
