# Error code E0585

A documentation comment that doesn't document anything was found.

Erroneous code example:

    fn main() {
        // The following doc comment will fail:
        /// This is a useless doc comment!
    }

Documentation comments need to be followed by items, including functions, types, modules, etc. Examples:

    #![allow(unused)]
    fn main() {
    /// I'm documenting the following struct:
    struct Foo;

    /// I'm documenting the following function:
    fn foo() {}
    }
