manual_unwrap_or_default ​

Source Code

What it does ​

Checks for manual unwrapping of an Option or Result.

Example ​

cairo
fn main() {
    let x: Option<u128> = Option::Some(1038);
    if let Option::Some(v) = x {
        v
    } else {
        0
    };
}

Can be simplified to:

cairo
fn main() {
    let x: Option<u128> = Option::Some(1038);
    x.unwrap_or_default();
}
