Module bones_lib::ecs::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.
