# Error code E0550

#### Note: this error code is no longer emitted by the compiler

More than one `deprecated` attribute has been put on an item.

Erroneous code example:

    #![allow(unused)]
    fn main() {
    #[deprecated(note = "because why not?")]
    #[deprecated(note = "right?")] // error!
    fn the_banished() {}
    }

The `deprecated` attribute can only be present once on an item.

    #![allow(unused)]
    fn main() {
    #[deprecated(note = "because why not, right?")]
    fn the_banished() {} // ok!
    }
