Module ecs Copy item path Source alloc The Rust core allocation and collections library commands components hierarchy life_cycle pipeline spin This crate provides spin-based versions of the
primitives in std::sync and std::lazy. Because synchronization is done through spinning,
the primitives are suitable for use in no_std environments. Archetype A collection of entities having the same component types ArchetypeColumn Shared reference to a single column of component data in an Archetype ArchetypeColumnMut Unique reference to a single column of component data in an Archetype ArchetypesGeneration Determines freshness of information derived from World::archetypes Batch A sequence of entities yielded by BatchedIter BatchIncomplete Error indicating that a ColumnBatchBuilder BatchWriter Handle for appending components BatchedIter Batched version of QueryIter BuiltEntity The output of an EntityBuilderWorld::spawnWorld::insert BuiltEntityClone A collection of components that implement Clone ChangeTracker Helper to track changes in T components Changes Collection of iterators over changes in T components ColumnBatch A collection of component data for entities with the same component types ColumnBatchBuilder An incomplete collection of component data for entities with the same component types ColumnBatchType A collection of component types CommandBuffer Records operations for future application to a World Comp DynamicClone Type-erased Clone Entity Lightweight unique ID, or handle, of an entity EntityBuilder Helper for incrementally constructing a bundle of components with dynamic component types EntityBuilderClone Variant of EntityBuilder EntityRef Handle to an entity with any component types Iter Iterator over all of a world’s entities MissingComponent Error indicating that an entity did not have a required component Multiverse NoSuchEntity Error indicating that no entity with a particular ID exists PreparedQuery A prepared query can be stored independently of the World PreparedQueryBorrow Combined borrow of a PreparedQueryWorld PreparedQueryIter Iterates over all entities matching a PreparedQuery PreparedView Provides random access to the results of a prepared query QueryBorrow A borrow of a WorldQ QueryIter Iterator over the set of entities with the components in Q QueryMut A query builder that’s convertible directly into an iterator QueryOne A borrow of a WorldQ on a single entity Ref Shared borrow of an entity’s component RefMut Unique borrow of an entity’s component RefRead RefWrite ResRead ResWrite Satisfies A query that matches all entities, yielding bools indicating whether each satisfies query Q SpawnBatchIter Entity IDs created by World::spawn_batch SpawnColumnBatchIter Iterator over EntityWorld::spawn_column_batch() TakenEntity An entity removed from a World TypeInfo Metadata required to store a component. Universe UnsafeMut UnsafeRef UnsafeScope View Provides random access to the results of a query ViewBorrow A borrow of a WorldQ.

This is primarily useful for unit tests. dynamic_bundle_satisfies_query Checks if a query is satisfied by a dynamic bundle. For static bundles, see bundle_satisfies_query .
