Type Alias NrosRmwNode 

pub type NrosRmwNode = rmw_node_t;

Phase 376 W5/B1 — a graph node. The first argument of the four create_* slots, in place of the fabricated per-call session view they used to take.

pub struct NrosRmwNode {
    pub name: *const i8,

Fields

name: *const i8

Node name. Borrowed; outlives the node.

namespace_: *const i8

Node namespace. Borrowed; outlives the node.

session: *mut rmw_session_t

The session this node lives on — upstream’s context. Set by the runtime before create_node; never NULL in a node the runtime hands to a slot. A backend reaches its own session state through node->session->backend_data.

_reserved: [u8; 8]

Reserved; must be zero.

backend_data: *mut c_void

Opaque backend state. NULL until create_node succeeds.
