# Error code E0572

A return statement was found outside of a function body.

Erroneous code example:

    const FOO: u32 = return 0; // error: return statement outside of function body

    fn main() {}

To fix this issue, just remove the return keyword or move the expression into a function. Example:

    const FOO: u32 = 0;

    fn some_fn() -> u32 {
        return FOO;
    }

    fn main() {
        some_fn();
    }
