Traits

• BitSet
  The BitSet API.
• ComponentIterBitset
  This trait factors out functions for iterating with bitset over component store. Separated from impl ComponentStore for usage in generic trait types that must be able to create ComponentBitsetIterator and related types.
• FromType
  Trait implemented for types that can produce an instance of themselves from a Rust type.
• FromWorld
  Creates an instance of the type this trait is implemented for using data from the supplied World.
• GenCore
  This trait provides the means to easily generate all integer types, provided the main method underpinning this is implemented: GenCore::gen. Once implemented, the rest of the trait provides default implementations for generating all integer types, though it is not recommended to override these.
• HasSchema
  Trait implemented for types that have a [Schema].
• IntoSystem
  Converts a function into a System.
• QueryItem
  A type representing a component-joining entity query.
• StageLabel
  Trait for things that may be used to identify a system stage.
• System
  Trait implemented by systems.
• SystemParam
  Trait used to implement parameters for System functions.
• SystemStage
  Trait for system stages. A stage is a
• TurboRand
  Extension trait for automatically implementing all TurboRand methods, as long as the struct implements [TurboCore] & GenCore. All methods are provided as default implementations that build on top of [TurboCore] and GenCore, and thus are not recommended to be overridden, lest you potentially change the expected outcome of the methods.
• UlidExt
  Extension trait for Ulid.
• UnwrapMany
  Helper trait for unwraping each item in an array.

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.
• create_bitset
  Creates a bitset big enough to contain the index of each entity. Mostly used to create caches.
• default
  An ergonomic abbreviation for Default::default() to make initializing structs easier. This is especially helpful when combined with “struct update syntax”.
• get_short_name
  Shortens a type name to remove all module paths.
• likely
  Hints to the compiler that the branch condition is likely to be true. Returns the value passed to it.
