# Error code E0708

#### Note: this error code is no longer emitted by the compiler.

`async` non-`move` closures with parameters are currently not supported.

Erroneous code example:

    fn main() {
        let add_one = async |num: u8| {
            num + 1
        };
    }

`async` with non-move is currently not supported with the current version, you can use successfully by using move:

    fn main() {
        let add_one = async move |num: u8| { // ok!
            num + 1
        };
    }
