Module node

Expand description

Rust component API shared by metadata discovery and generated runtimes.

Structs§

Callback: Runtime callback event delivered to an executable Node.
CallbackCtx
CallbackEffects: Builder for optional callback effect metadata.
EntityBounds: phase-391 W5-endgame step 2c (issue 0857) — a component class’s declared upper bounds, PER ENTITY KIND, for sizing its cell registries at compile time.
NodeActionClient: Source-level component entity handle.
NodeActionServer: Source-level component entity handle.
NodeContext: Node declaration context — what a component’s register receives.
NodeOptions: Runtime-neutral node construction options.
NodeParameter: Source-level component entity handle.
NodePublisher: Source-level component entity handle.
NodeServiceClient: Source-level component entity handle.
NodeServiceServer: Source-level component entity handle.
NodeSubscription: Source-level component entity handle.
NodeTimer: Source-level component entity handle.
TickCtx: Context handed to ExecutableNode::tick (W.5.6 + M-F.4): the per-spin hook that runs between callback dispatch, where the executor is free. Exposes the immediate publish path (like CallbackCtx) plus executor-backed action-server ops (complete goal / publish feedback) AND executor-backed client-side ops (service call / action-client send_goal). Callbacks can’t perform any of these since they don’t hold the executor.

ActionExecutor: The executable counterpart of Component (W.5.1).
ClientDispatch: Executor-backed CLIENT operations a TickCtx drives (Phase 212.M-F.4).
Component: Rust component entry point.
DeclarativeNode: phase-483 W3 — the DECLARATIVE entity constructors, on the one node type.
ExecutableNode
NodeRuntime: Declaration sink implemented by metadata recorders and generated runtimes.
PublisherResolver: Resolves a component publisher by its stable EntityId for the callback-body publish path (W.5.1).

record_node_metadata: Run component registration against an in-memory metadata recorder, on an executor the caller opened on the metadata backend.
register_node: Run component registration against a metadata recorder, on executor.
