Error code E0430

The self import appears more than once in the list.

Erroneous code example:

#![allow(unused)]
fn main() {
use something::{self, self}; // error: `self` import can only appear once in
                             //        the list
}

Please verify you didn’t misspell the import name or remove the duplicated self import. Example:

mod something {}
fn main() {
use something::{self}; // ok!
}
