## Objective There's no general error for when an entity doesn't exist, and some methods are going to need one when they get Resultified. The closest thing is `EntityFetchError`, but that error has a slightly more specific purpose. ## Solution - Added `EntityDoesNotExistError`. - Contains `Entity` and `EntityDoesNotExistDetails`. - Changed `EntityFetchError` and `QueryEntityError`: - Changed `NoSuchEntity` variant to wrap `EntityDoesNotExistError` and renamed the variant to `EntityDoesNotExist`. - Renamed `EntityFetchError` to `EntityMutableFetchError` to make its purpose clearer. - Renamed `TryDespawnError` to `EntityDespawnError` to make it more general. - Changed `World::inspect_entity` to return `Result<[ok], EntityDoesNotExistError>` instead of panicking. - Changed `World::get_entity` and `WorldEntityFetch::fetch_ref` to return `Result<[ok], EntityDoesNotExistError>` instead of `Result<[ok], Entity>`. - Changed `UnsafeWorldCell::get_entity` to return `Result<UnsafeEntityCell, EntityDoesNotExistError>` instead of `Option<UnsafeEntityCell>`. ## Migration Guide - `World::inspect_entity` now returns `Result<impl Iterator<Item = &ComponentInfo>, EntityDoesNotExistError>` instead of `impl Iterator<Item = &ComponentInfo>`. - `World::get_entity` now returns `EntityDoesNotExistError` as an error instead of `Entity`. You can still access the entity's ID through the error's `entity` field. - `UnsafeWorldCell::get_entity` now returns `Result<UnsafeEntityCell, EntityDoesNotExistError>` instead of `Option<UnsafeEntityCell>`. |
