Boxy eabcd27d93 make WorldQuery very flat (#5205) ... # Objective Simplify the worldquery trait hierarchy as much as possible by putting it all in one trait. If/when gats are stabilised this can be trivially migrated over to use them, although that's not why I made this PR, those reasons are: - Moves all of the conceptually related unsafe code for a worldquery next to eachother - Removes now unnecessary traits simplifying the "type system magic" in bevy_ecs --- ## Changelog All methods/functions/types/consts on `FetchState` and `Fetch` traits have been moved to the `WorldQuery` trait and the other traits removed. `WorldQueryGats` now only contains an `Item` and `Fetch` assoc type. ## Migration Guide Implementors should move items in impls to the `WorldQuery/Gats` traits and remove any `Fetch`/`FetchState` impls Any use sites of items in the `Fetch`/`FetchState` traits should be updated to use the `WorldQuery` trait items instead Co-authored-by: Carter Anderson <mcanders1@gmail.com>		2022-08-04 21:51:02 +00:00
