Struct bones_lib::ecs::prelude::SystemStages

pub struct SystemStages {
    pub stages: Vec<Box<dyn SystemStage>>,
    pub has_started: bool,
    pub startup_systems: Vec<StaticSystem<(), ()>>,
}

An ordered collection of SystemStages.

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.

Implementations

impl SystemStages

pub fn run(&mut self, world: &mut World)

Execute the systems on the given world.

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 SystemStageswhere S: IntoSystem<Args, (), (), Sys = StaticSystem<(), ()>>,

Add a system that will run only once, before all of the other non-startup systems.

pub fn add_system_to_stage<Args, S>( &mut self, label: impl StageLabel, system: S ) -> &mut SystemStageswhere S: IntoSystem<Args, (), (), Sys = StaticSystem<(), ()>>,

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,

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,

Insert a new stage, after another existing stage
