Module specs::world [−] [src]

Entities, resources, components, and general world management.

Structs

CreateIter	An iterator for entity creation. Please note that you have to consume it because iterators are lazy.
CreateIterAtomic	An iterator for entity creation. Please note that you have to consume it because iterators are lazy.
EntitiesRes	The entities of this ECS. This is a resource, stored in the `World`. If you just want to access it in your system, you can also use the `Entities` type def.
Entity	`Entity` type, as seen by the user.
EntityBuilder	The entity builder, allowing to build an entity together with its components.
Generation	Index generation. When a new entity is placed at an old index, it bumps the `Generation` by 1. This allows to avoid using components from the entities that were deleted.
LazyBuilder	Like `EntityBuilder`, but inserts the component lazily, meaning on `maintain`. If you need those components to exist immediately, you have to insert them into the storages yourself.
LazyUpdate	Lazy updates can be used for world updates that need to borrow a lot of resources and as such should better be done at the end. They work lazily in the sense that they are dispatched when calling `world.maintain()`.
World	The `World` struct contains the component storages and other resources.

Bundle	Trait used to bundle up resources/components for easy registration with `World`.
Component	Abstract component type. Doesn't have to be Copy or even Clone.

Entities	A wrapper for a read `Entities` resource. Note that this is just `Read<Entities>`, so you can easily use it in your system:
Index	An index is basically the id of an `Entity`.
