Destructuring Tuples with let

Snippet

Destructuring Tuples with let

Tuples can be unpacked directly in a let binding, allowing you to extract individual values into named variables. Use underscores to ignore values you don't need.

snippet.rs
rust
fn main() {
    let point = (10, 20, 30);
    let (x, y, z) = point;
    println!("X: {}, Y: {}, Z: {}", x, y, z);
    
    let (_ignore, middle, _) = (100, 200, 300);
    println!("Middle value: {}", middle);
}

Breakdown

let point = (10, 20, 30);

Creates a tuple with three i32 values

let (x, y, z) = point;

Destructures the tuple into three separate variables

let (_ignore, middle, _) = (100, 200, 300);

Unpacks while ignoring first and last values using underscore
