Module bevy_internal::ecs::change_detection

Types that detect when their internal data mutate.

Structs

• Mut
  Unique mutable borrow of an entity’s component or of a resource.
• MutUntyped
  Unique mutable borrow of resources or an entity’s component.
• NonSendMut
  Unique borrow of a non-Send resource.
• Ref
  Shared borrow of an entity’s component with access to change detection. Similar to Mut but is immutable and so doesn’t require unique access.
• Res
  Shared borrow of a Resource.
• ResMut
  Unique mutable borrow of a Resource.

Constants

• CHECK_TICK_THRESHOLD
  The (arbitrarily chosen) minimum number of world tick increments between check_tick scans.
• MAX_CHANGE_AGE
  The maximum change tick difference that won’t overflow before the next check_tick scan.

Traits

• DetectChanges
  Types that can read change detection information. This change detection is controlled by DetectChangesMut types such as ResMut.
• DetectChangesMut
  Types that implement reliable change detection.
