Module oxygengine::core::ecs::storage

Component storage types, implementations for component joins, etc.

Structs

AntiStorage	An inverted storage type, only useful to iterate entities that do not have a particular component type.
BTreeStorage	BTreeMap-based storage.
Entries	Join-able structure that yields all indices, returning Entry for all elements
MaskedStorage	The UnprotectedStorage together with the BitSet that knows about which elements are stored, and which are not.
OccupiedEntry	An entry to a storage which has a component associated to the entity.
RestrictedStorage	Similar to a MaskedStorage and a Storage combined, but restricts usage to only getting and modifying the components. That means it's not possible to modify the inner bitset so the iteration cannot be invalidated. In other words, no insertion or removal is allowed.
VacantEntry	An entry to a storage which does not have a component associated to the entity.

Enums

ImmutableParallelRestriction	Specifies that the RestrictedStorage can run in parallel immutably.
MutableParallelRestriction	Specifies that the RestrictedStorage can run in parallel mutably.
SequentialRestriction	Specifies that the RestrictedStorage cannot run in parallel.
StorageEntry	Entry to a storage for convenient filling of components or removal based on whether the entity has a component.

Traits

AnyStorage	A dynamic storage.
DistinctStorage	This is a marker trait which requires you to uphold the following guarantee:
GenericReadStorage	Provides generic read access to both ReadStorage and WriteStorage
GenericWriteStorage	Provides generic write access to WriteStorage, both as a value and a mutable reference.
TryDefault	Tries to create a default value, returns an Err with the name of the storage and/or component if there's no default.
UnprotectedStorage	Used by the framework to quickly join components.

Type Definitions

InsertResult

The status of an insert()ion into a storage. If the insertion was successful then the Ok value will contain the component that was replaced (if any).
