## Problem - The `Query` struct does not provide an easy way to check if it is empty. - Specifically, users have to use `.iter().peekable()` or `.iter().next().is_none()` which is not very ergonomic. - Fixes: #2270 ## Solution - Implement an `is_empty` function for queries to more easily check if the query is empty. |
