Struct bones_lib::render::prelude::SystemStages

pub struct SystemStages {
    pub stages: Vec<Box<dyn SystemStage + 'static, Global>, Global>,
}

An ordered collection of SystemStages.

Fields

stages: Vec<Box<dyn SystemStage + 'static, Global>, Global>

The stages in the collection, in the order that they will be run.

Implementations

impl SystemStages

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

Initialize the systems in the stages agains the World.

This must be called once before calling run().

pub fn run(&mut self, world: &mut World) -> Result<(), Error>

Execute the systems on the given world.

Note: You must call initialize_systems() once before calling run() one or more times.

pub fn with_core_stages() -> SystemStages

Create a SystemStages collection, initialized with a stage for each CoreStage.

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

Add a System to the stage with the given label.

pub fn insert_stage_before<L, S>(&mut self, label: L, stage: S)where
    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)where
    L: StageLabel,
    S: SystemStage + 'static,

Insert a new stage, after another existing stage
