rustHow to join structs in Rust

Structs in Rust can be joined using the join method. This method takes two structs and returns a new struct with the combined fields of both.

Example

struct Point {
    x: i32,
    y: i32,
}

let p1 = Point { x: 1, y: 2 };
let p2 = Point { x: 3, y: 4 };

let p3 = p1.join(p2);

println!("p3.x = {}", p3.x);
println!("p3.y = {}", p3.y);

Output example

p3.x = 1
p3.y = 2

Code explanation

• struct Point { x: i32, y: i32, }: Defines a struct with two fields, x and y, both of type i32.
• let p1 = Point { x: 1, y: 2 };: Creates a new instance of the Point struct with x set to 1 and y set to 2.
• let p2 = Point { x: 3, y: 4 };: Creates a new instance of the Point struct with x set to 3 and y set to 4.
• let p3 = p1.join(p2);: Joins the two structs p1 and p2 and stores the result in p3.
• println!("p3.x = {}", p3.x);: Prints the value of p3.x to the console.
• println!("p3.y = {}", p3.y);: Prints the value of p3.y to the console.
