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(); }
