Rust struct update syntax Link to heading

I recently came across some syntax in Rust that I was not familiar with from other languages, so I wanted to make a note of this syntax: struct update syntax with ..

// Define a struct with four fields
struct Point {
    x: i32,
    y: i32,
    z: i32,
    w: i32,
}

// Create an instance of Point with default values
let origin = Point { x: 0, y: 0, z: 0, w: 0 };

// Create a new instance of Point that has the same values as origin
// except for the x field, which is 1
let point = Point { x: 1, ..origin };

// Print the values of point
println!("point.x = {}, point.y = {}, point.z = {}, point.w = {}", point.x, point.y, point.z, point.w);

It turns out that this syntax is not new to Rust — other languages, such as Haskell, Elm, TypeScript, and JavaScript has a similar feature. I am not too familiar with any of those languages, so it was a first time for me.
