The compiler team's explanation
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();
