Modules

asset
changeset	Provides a changeset that can be collected from an iterator.
database
engines
error	Specs errors
fs
join	Joining of components for iteration over entities with specific components.
map
protocol
protocols
shred	Shared resource dispatcher
storage	Component storage types, implementations for component joins, etc.
system
world	Entities, resources, components, and general world management.

App
AppBuilder
AppLifeCycle
AppRunner
AssetsDatabase
AssetsSystem
BitSet	A `BitSet` is a simple set designed to track which indices are placed into it.
DenseVecStorage	Dense vector storage. Has a redirection 2-way table between entities and components, allowing to leave no gaps within the data.
EmptyState
FetchProcess
FsFetchEngine
ID	Universal Identifier (uuidv4).
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()`.
Parent
ReaderId	The reader id is used by readers to tell the storage where the last read ended.
SetAssetProtocol
StandardAppTimer
StaticAccessor	The static accessor that is used for `SystemData`.
SyncAppRunner
Tag

Accessor	A trait for accessing read/write multiple resources from a system. This can be used to create dynamic systems that don't specify what they fetch at compile-time.
AppTimer
BackendAppRunner
Component	Abstract component type. Doesn't have to be Copy or even Clone.
FetchEngine
FetchProcessReader
Join	The purpose of the `Join` trait is to provide a way to access multiple storages at the same time with the merged bit set.
State

AssetID
Entities	A wrapper for a read `Entities` resource. Note that this is just `Read<Entities>`, so you can easily use it in your system:
FetchProcessID
HierarchyRes
Meta
WriteExpect	Allows to fetch a resource in a system mutably. This will panic if the resource does not exist. Usage of `Write` or `Option<Write>` is therefore recommended.
WriteStorage	A storage with read and write access.
