Code

struct Point<T> {
    x: T,
    y: T,
}

impl<T: std::fmt::Display> Point<T> {
    fn display(&self) {
        println!("({}, {})", self.x, self.y);
    }
}

fn main() {
    let integer_point = Point { x: 5, y: 10 };
    let float_point = Point { x: 1.0, y: 4.0 };
    integer_point.display();
    float_point.display();
}

Explanation

This example demonstrates how to use generic struct in Rust. Read the code carefully to understand the flow. Pay attention to where values are created, borrowed, moved, or consumed.

Key Concepts

• Rust's strong type system catches errors at compile time
• Ownership and borrowing rules ensure memory safety
• Pattern matching makes code expressive and exhaustive
