`if let Some(x) = x or y`

[FallBackITA27]

Is there a way of doing the following with if-let syntax?

let x: Option<u32> = None;
let y: Option<u32> = Some(13);
if let Some(x) = x || y {
     // ... where x = Some(13)
}

I'm not sure I understand what you want to achieve. Do you want to enter the branch if either x or y is Some(13)? In which case you can just use Option::or:

fn main() {
    let x: Option<u32> = None;
    let y: Option<u32> = Some(13);
    
    if let Some(13) = x.or(y) {
        println!("yes");
    }
}

Playground.

If you want to bind the inner value of y if y is Some(_) to a variable if x is Some(13), you could pattern-match a tuple:

fn main() {
    let x: Option<u32> = Some(13);
    let y: Option<u32> = Some(42);
    
    if let (Some(13), Some(y_inner)) = (x, y) {
        println!("yes: {y_inner}");
    }
}
