Question

How to define structs to use a generic type parameter in Rust

Answer 1

#[derive(Debug)]

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

fn main() {
    let integer = Point { x: 45, y: 98 };

    println!("integer = {:?}", integer);
    println!("integer.x = {:?}", integer.x);
    println!("integer,y = {:?}", integer.y);
    
    let float = Point { x: 3.14, y: 6.21 };
    
    println!("float = {:?}", float);
    println!("float.x = {:?}", float.x);
    println!("float,y = {:?}", float.y);

}





/*
run:

integer = Point { x: 45, y: 98 }
integer.x = 45
integer,y = 98
float = Point { x: 3.14, y: 6.21 }
float.x = 3.14
float,y = 6.21
