What it does

Checks for empty lines after outer attributes

Why is this bad?

The attribute may have meant to be an inner attribute (#![attr]). If it was meant to be an outer attribute (#[attr]) then the empty line should be removed

Example

#[allow(dead_code)]

fn not_quite_good_code() {}

Use instead:

// Good (as inner attribute)
#![allow(dead_code)]

fn this_is_fine() {}

// or

// Good (as outer attribute)
#[allow(dead_code)]
fn this_is_fine_too() {}
