Modules

• error
  Contains error types returned by bevy’s schedule.
• unsafe_world_cell
  Contains types that allow disjoint mutable access to a World.

Structs

• EntityMut
  Provides mutable access to a single entity and all of its components.
• EntityRef
  A read-only reference to a particular Entity and all of its components.
• EntityWorldMut
  A mutable reference to a particular Entity, and the entire world. This is essentially a performance-optimized (Entity, &mut World) tuple, which caches the EntityLocation to reduce duplicate lookups.
• SpawnBatchIter
  An iterator that spawns a series of entities and returns the ID of each spawned entity.
• World
  Stores and exposes operations on entities, components, resources, and their associated metadata.
• WorldBorrow
  A read-only borrow of some data stored in a World. This type is returned by WorldCell, which uses run-time checks to ensure that the borrow does not violate Rust’s aliasing rules.
• WorldBorrowMut
  A mutable borrow of some data stored in a World. This type is returned by WorldCell, which uses run-time checks to ensure that the borrow does not violate Rust’s aliasing rules.
• WorldCell
  Exposes safe mutable access to multiple resources at a time in a World. Attempting to access World in a way that violates Rust’s mutability rules will panic thanks to runtime checks.
• WorldId
  A unique identifier for a World.

Traits

• FromWorld
  Creates an instance of the type this trait is implemented for using data from the supplied World.
