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

AssetsSystem
BitSet	A `BitSet` is a simple set designed to track which indices are placed into it.
ChangeSet	Change set that can be collected from an iterator, and joined on for easy application to components.
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
HashMapStorage	HashMap-based storage. Best suited for rare components.
ID	Universal Identifier (uuidv4).
NullStorage	A null storage type, used for cases where the component doesn't contain any data and instead works as a simple flag.
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
Write	Allows to fetch a resource in a system mutably.

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
Builder	A common trait for `EntityBuilder` and `LazyBuilder`, allowing either to be used. Entity is definitely alive, but the components may or may not exist before a call to `World::maintain`.
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.

AssetID
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.
