Error code E0648

An export_name attribute contains null characters (\0).

Erroneous code example:

#![allow(unused)] fn main() { #[export_name="\0foo"] // error: `export_name` may not contain null characters pub fn bar() {} }

To fix this error, remove the null characters:

#![allow(unused)] fn main() { #[export_name="foo"] // ok! pub fn bar() {} }
