BD103 04ceb46fe0 Use EntityHashMap for EntityMapper (#10415) ... # Objective - There is a specialized hasher for entities: [`EntityHashMap`](https://docs.rs/bevy/latest/bevy/utils/type.EntityHashMap.html) - [`EntityMapper`] currently uses a normal `HashMap<Entity, Entity>` - Fixes #10391 ## Solution - Replace the normal `HashMap` with the more performant `EntityHashMap` ## Questions - This does change public API. Should a system be implemented to help migrate code? - Perhaps an `impl From<HashMap<K, V, S>> for EntityHashMap<K, V>` - I updated to docs for each function that I changed, but I may have missed something --- ## Changelog - Changed `EntityMapper` to use `EntityHashMap` instead of normal `HashMap` ## Migration Guide If you are using the following types, update their listed methods to use the new `EntityHashMap`. `EntityHashMap` has the same methods as the normal `HashMap`, so you just need to replace the name. ### `EntityMapper` - `get_map` - `get_mut_map` - `new` - `world_scope` ### `ReflectMapEntities` - `map_all_entities` - `map_entities` - `write_to_world` ### `InstanceInfo` - `entity_map` - This is a property, not a method. --- This is my first time contributing in a while, and I'm not familiar with the usage of `EntityMapper`. I changed the type definition and fixed all errors, but there may have been things I've missed. Please keep an eye out for me!		2023-11-07 08:23:04 +00:00
