-//! Trait queries support basic change detection filtration. So to get all the components that
-//! implement the target trait, and have also changed in some way since the last tick, you can:
-//! ```ignore
-//! fn show_tooltips(
-//!     tooltips: Query<ChangedAll<&dyn Tooltip>>
-//!     // ...
-//! ) {
-//!     for tooltip in &tooltips {
-//!         println!("changed tool tips: {}", tooltip.tooltip());
-//!     }
-//! }

-//! Similarly, there exist `ChangedOne`, `AddedOne`, and `AddedAll`.

 //! The performance of trait queries is quite competitive. Here are some benchmarks for simple cases:
