Struct jumpy::prelude::SystemStages
pub struct SystemStages {
pub stages: Vec<Box<dyn SystemStage>>,
pub has_started: bool,
pub startup_systems: Vec<StaticSystem<(), ()>>,
pub single_success_systems: Vec<StaticSystem<(), Option<()>>>,
}
Expand description
An ordered collection of SystemStage
s.
Fields§
§stages: Vec<Box<dyn SystemStage>>
The stages in the collection, in the order that they will be run.
has_started: bool
Whether or not the startup systems have been run yet.
startup_systems: Vec<StaticSystem<(), ()>>
The systems that should run at startup.
single_success_systems: Vec<StaticSystem<(), Option<()>>>
Systems that are continously run until they succeed(return Some). These run before all stages. Uses Option to allow for easy usage of ?
.
Implementations§
§impl SystemStages
impl SystemStages
pub fn with_core_stages() -> SystemStages
pub fn with_core_stages() -> SystemStages
Create a SystemStages
collection, initialized with a stage for each CoreStage
.
pub fn add_startup_system<Args, S>(&mut self, system: S) -> &mut SystemStages
pub fn add_startup_system<Args, S>(&mut self, system: S) -> &mut SystemStages
Add a system that will run only once, before all of the other non-startup systems.
pub fn add_single_success_system<Args, S>(
&mut self,
system: S,
) -> &mut SystemStages
pub fn add_single_success_system<Args, S>( &mut self, system: S, ) -> &mut SystemStages
Add a system that will run each frame until it succeeds (returns Some). Runs before all stages. Uses Option to allow for easy usage of ?
.
pub fn add_system_to_stage<Args, S>(
&mut self,
label: impl StageLabel,
system: S,
) -> &mut SystemStages
pub fn add_system_to_stage<Args, S>( &mut self, label: impl StageLabel, system: S, ) -> &mut SystemStages
Add a System
to the stage with the given label.
pub fn insert_stage_before<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStageswhere
L: StageLabel,
S: SystemStage + 'static,
pub fn insert_stage_before<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStageswhere
L: StageLabel,
S: SystemStage + 'static,
Insert a new stage, before another existing stage
pub fn insert_stage_after<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStageswhere
L: StageLabel,
S: SystemStage + 'static,
pub fn insert_stage_after<L, S>(
&mut self,
label: L,
stage: S,
) -> &mut SystemStageswhere
L: StageLabel,
S: SystemStage + 'static,
Insert a new stage, after another existing stage
pub fn reset_remove_all_systems(&mut self)
pub fn reset_remove_all_systems(&mut self)
Remove all systems from all stages, including startup and single success systems. Resets has_started as well, allowing for startup systems to run once again.
pub fn remove_all_systems(&mut self)
pub fn remove_all_systems(&mut self)
Remove all systems from all stages, including startup and single success systems. Does not reset has_started.
