Struct NodeContext 

pub struct NodeContext<'a, R: NodeRuntime + ?Sized = dyn NodeRuntime + 'a> { /* private fields */ }

Node declaration context. Does not own middleware transport.

Implementations

impl<'a, R: NodeRuntime + ?Sized> NodeContext<'a, R>

pub fn new(component_name: &'static str, runtime: &'a mut R) -> Self

Build a context over a metadata recorder or generated runtime.

pub fn set_params(&mut self, params: &'a [(&'a str, &'a str)])

Phase 264 W4a — seed this node instance’s baked launch parameters (called by install_node_typed_with_params before Node::register).

pub fn param(&self, name: &str) -> Option<&'a str>

Phase 264 W4a — the baked initial value of launch parameter name, or None if the launch declared no <param name="…"/> for this node instance. Read in register() and parse/stash on State (RFC-0004 §10).

pub const fn component_name(&self) -> &'static str

Source component name.

pub fn create_node<'id>( &mut self, options: NodeOptions<'id>, ) -> NodeResult<DeclaredNode<'_, 'id, R>>

Declare a node using options.name as the stable node ID.

This mirrors the common rclcpp/rclrs shape where a node package supplies node options and the node name, while nano-ros keeps the generated stable ID as internal metadata.

pub fn create_node_with_options<'id>( &mut self, options: NodeOptions<'id>, ) -> NodeResult<DeclaredNode<'_, 'id, R>>

👎Deprecated:

use create_node(NodeOptions)

Deprecated alias for create_node.
