Struct RenderFlow 

pub struct RenderFlow;

Projects the ECS World into the per-frame RenderWorld consumed by the render lanes.

Trait Implementations

impl Default for RenderFlow

fn default() -> RenderFlow

Returns the “default value” for a type.

impl Flow for RenderFlow

fn cache_key(&self, world: &World, runtime: &Runtime) -> Option<u64>

The projection below reads mesh/material handles, Light and Camera (Render domain), GlobalTransform (Spatial domain), and — through primary_view — the editor viewport override, which is runtime state with no ECS epoch. Folding its bit-level fingerprint into the key keeps editor camera motion from serving stale views.

const DOMAIN: SemanticDomain = SemanticDomain::Render

Domain identifier — matches the agent’s domain.

const NAME: &'static str = "render"

Stable identifier — used for telemetry and ordering.

type View = RenderWorld

The typed view this Flow publishes into the LaneBus. Clone so the registration trampoline can republish a cached view without re-running select/project (views hold Arcs and plain data, so cloning is cheap relative to a full re-projection).

fn project( &self, world: &World, _sel: &Selection, runtime: &Runtime, ) -> Self::View

Stage 2 — read-only projection of the world into a View.

fn select(&mut self, world: &World, runtime: &Runtime) -> Selection

Stage 1 — read-only selection of relevant entities.
