Module bevy::ecs::schedule

Contains APIs for ordering systems and executing them on a World

Modules

• common_conditions
  A collection of run conditions that may be useful in any bevy app.

Structs

• AnonymousSet
  A SystemSet implicitly created when using Schedule::add_systems or Schedule::configure_sets.
• Dag
  A directed acyclic graph structure.
• MainThreadExecutor
  New-typed ThreadExecutor Resource that is used to run systems on the main thread
• MultiThreadedExecutor
  Runs the schedule using a thread pool. Non-conflicting systems can run in parallel.
• NextState
  The next state of State<S>.
• NodeConfig
  Stores configuration for a single generic node.
• OnEnter
  The label of a Schedule that runs whenever State<S> enters this state.
• OnExit
  The label of a Schedule that runs whenever State<S> exits this state.
• OnTransition
  The label of a Schedule that only runs whenever State<S> exits the from state, AND enters the to state.
• Schedule
  A collection of systems, and the metadata and executor needed to run them in a certain order under certain conditions.
• ScheduleBuildSettings
  Specifies miscellaneous settings for schedule construction.
• ScheduleGraph
  Metadata for a Schedule.
• ScheduleNotInitialized
  Error to denote that Schedule::initialize or Schedule::run has not yet been called for this schedule.
• Schedules
  Resource that stores Schedules mapped to ScheduleLabels excluding the current running Schedule.
• SimpleExecutor
  A variant of SingleThreadedExecutor that calls apply_deferred immediately after running each system.
• SingleThreadedExecutor
  Runs the schedule using a single thread.
• State
  A finite-state machine whose transitions have associated schedules ([OnEnter(state)] and [OnExit(state)]).
• StateTransitionEvent
  Event sent when any state transition of S happens.
• Stepping
  Resource for controlling system stepping behavior
• SystemSchedule
  Holds systems and conditions of a Schedule sorted in topological order (along with dependency information for multi-threaded execution).
• SystemTypeSet
  A SystemSet grouping instances of the same function.

Enums

• Chain
  Chain systems into dependencies
• ExecutorKind
  Specifies how a Schedule will be run.
• LogLevel
  Specifies how schedule construction should respond to detecting a certain kind of issue.
• NodeConfigs
  A collections of generic NodeConfigs.
• NodeId
  Unique identifier for a system or system set stored in a ScheduleGraph.
• ScheduleBuildError
  Category of errors encountered during schedule construction.

Traits

• Condition
  A system that determines if one or more scheduled systems should run.
• DynEq
  An object safe version of Eq. This trait is automatically implemented for any 'static type that implements Eq.
• IntoSystemConfigs
  Types that can convert into a SystemConfigs.
• IntoSystemSet
  Types that can be converted into a SystemSet.
• IntoSystemSetConfigs
  Types that can convert into a SystemSetConfigs.
• ScheduleLabel
  A strongly-typed class of labels used to identify an [Schedule].
• States
  Types that can define world-wide states in a finite-state machine.
• SystemSet
  Types that identify logical groups of systems.

Functions

• apply_deferred
  Instructs the executor to call System::apply_deferred on the systems that have run but not applied their Deferred system parameters (like Commands) or other system buffers.
• apply_state_transition
  If a new state is queued in NextState<S>, this system:
• run_enter_schedule
  Run the enter schedule (if it exists) for the current state.

Type Aliases

• AndThen
  Combines the outputs of two systems using the && operator.
• BoxedCondition
  A type-erased run condition stored in a Box.
• InternedScheduleLabel
  A shorthand for Interned<dyn ScheduleLabel>.
• InternedSystemSet
  A shorthand for Interned<dyn SystemSet>.
• NotSystem
  Invokes Not with the output of another system.
• OrElse
  Combines the outputs of two systems using the || operator.
• SystemConfig
  Stores configuration for a single system.
• SystemConfigs
  A collection of SystemConfig.
• SystemSetConfig
  A SystemSet with scheduling metadata.
• SystemSetConfigs
  A collection of SystemSetConfig.

Derive Macros

• ScheduleLabel
  Derive macro generating an impl of the trait ScheduleLabel.
• States
• SystemSet
  Derive macro generating an impl of the trait SystemSet.
