Module node 

Rust component API shared by metadata discovery and generated runtimes.

Structs

Callback

Runtime callback event delivered to an executable Node.

CallbackCtx

Context handed to an executable component callback body (W.5.1).

CallbackEffects

Builder for optional callback effect metadata.

DeclaredNode

Declared component node.

NodeActionClient

Source-level component entity handle.

NodeActionServer

Source-level component entity handle.

NodeContext

Node declaration context. Does not own middleware transport.

NodeOptions

Runtime-neutral node construction options.

NodeParameter

Source-level component entity handle.

NodePublisher

Source-level component entity handle.

NodeRuntimeAdapter

Runtime adapter used by generated main ownership code.

NodeServiceClient

Source-level component entity handle.

NodeServiceServer

Source-level component entity handle.

NodeSubscription

Source-level component entity handle.

NodeTimer

Source-level component entity handle.

RuntimeNodeRecord

Recorded runtime node mapping.

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.

Enums

NodeDeclError

Node declaration error.

Constants

MISSING_NODE_EXPORT_ERROR

Clear diagnostic for packages missing nros::node!.

Traits

ActionExecutor

The executable counterpart of Node (W.5.1).

ClientDispatch

Executor-backed CLIENT operations a TickCtx drives (Phase 212.M-F.4).

DeclaredNodeRuntime

Runtime node sink used by generated component executors.

ExecutableNode

Node

Rust component entry point.

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).

Functions

record_node_metadata

Run component registration against an in-memory metadata recorder.

register_node

Run component registration against any component runtime.

Type Aliases

NodeExecutorRuntime

Runtime adapter backed by Executor.

NodeResult

Result type for component declarations.
