| First | The first element matching all the criteria, or null if none was found. |
| ForEach | Invokes function on all elements matching the query. |
| GetEnumerator | Allows traversing the results of the query with foreach without creating GC allocations. |
| Last | The last element matching all the criteria, or null if none was found. |
| RebuildOn | Creates a new QueryState with the same selection rules, applied on another VisualElement. |
| ToList | Adds all elements satisfying selection rules to the list. |
