Module entities 

Entity implementation, storage, and interation.

Structs

Entities

Holds a list of alive entities.

EntitiesIterWith

Iterator over entities returned by Entities::iter_with.

Entity

An entity index.

EntityIterator

Iterator over entities using the provided bitset.

OptionalQueryItem

Wrapper for the Comp SystemParam used as QueryItem to iterate over entities optionally retrieving components from ComponentStore. Entities iterated over will not be filtered by OptionalQueryItem.

OptionalQueryItemMut

Wrapper for the CompMut SystemParam used as QueryItem to iterate over entities optionally and mutably retrieving components from ComponentStore. Entities iterated over will not be filtered by OptionalQueryItemMut.

Enums

QuerySingleError

An error that may occur when querying for a single entity. For example, via Entities::get_single_with, or more directly with ComponentStore::get_single_with_bitset or ComponentStore::get_single_mut_with_bitset.

Traits

QueryItem

A type representing a component-joining entity query.

Functions

Optional

Helper func to construct a OptionalQueryItem wrapping a Comp SystemParam. Used to iterate over enities optionally retrieving components from ComponentStore. Entities iterated over will not be filtered by this QueryItem.

OptionalMut

Helper func to construct a OptionalQueryItemMut wrapping a CompMut SystemParam. Used to iterate over enities optionally and mutably retrieving components from ComponentStore. Entities iterated over will not be filtered by this QueryItem.
