# Error code E0260

The name for an item declaration conflicts with an external crate's name.

Erroneous code example:

    extern crate core;

    struct core;

    fn main() {}

There are two possible solutions:

Solution #1: Rename the item.

    #![allow(unused)]
    fn main() {
    extern crate core;

    struct xyz;
    }

Solution #2: Import the crate with a different name.

    #![allow(unused)]
    fn main() {
    extern crate core as xyz;

    struct abc;
    }

See the Declaration Statements section of the reference for more information about what constitutes an item declaration and what does not.
