Struct Runtime 

pub struct Runtime {
    pub services: Services,
    pub backends: Backends,
    pub resources: Resources,
}
Expand description

Bundle of the three runtime containers.

Engine init builds one Runtime (mutating its containers freely), then wraps it in an Arc<Runtime> and stores it in EngineContext. After that point the bundle is immutable for the rest of the engine lifetime.

Lanes, agents, flows, and data systems receive &Runtime and look up what they need with runtime.services.get::<X>(), runtime.backends.get::<X>(), or runtime.resources.get::<X>().

Fields§

§services: Services

Stateful business-logic objects (AssetService, …).

§backends: Backends

Concrete trait implementations (RenderSystem, …).

§resources: Resources

Long-lived shared state (InputMap, …).

Implementations§

§

impl Runtime

pub fn new() -> Runtime

Creates an empty bundle (all three containers empty).
