Field Documentation

_opaque

uint64_t nros_subscription_t::_opaque[SUBSCRIPTION_OPAQUE_U64S]

Phase 122.3.b — inline opaque storage for the L1 polling-mode RawSubscription<MESSAGE_BUFFER_SIZE>. Zeroed in callback (L2) mode; populated by nros_subscription_init_polling.

callback

nros_subscription_callback_t nros_subscription_t::callback

User callback function

context

void* nros_subscription_t::context

User context pointer

handle_id

size_t nros_subscription_t::handle_id

Handle ID from executor registration (SIZE_MAX = not registered)

node

const struct nros_node_t* nros_subscription_t::node

Pointer to parent node

qos

struct nros_qos_t nros_subscription_t::qos

QoS settings (stored during init, used by executor registration)

sched_context_id

nros_sched_context_id_t nros_subscription_t::sched_context_id

Phase 189.M3 — scheduling-context slot requested via [nros_subscription_init_with_options]. 0 = inherit the executor / Node default (no explicit bind), matching the nros_node_options_t::sched_context_id convention. When non-zero, nros_executor_register_subscription binds the freshly-created handle to this SC after registration. Has no effect on the L1 polling path (no executor handle to bind).

state

enum nros_subscription_state_t nros_subscription_t::state

Current state

topic_name

uint8_t nros_subscription_t::topic_name[256]

Topic name storage

topic_name_len

size_t nros_subscription_t::topic_name_len

Topic name length

type_hash

uint8_t nros_subscription_t::type_hash[128]

Type hash storage

type_hash_len

size_t nros_subscription_t::type_hash_len

Type hash length

type_name

uint8_t nros_subscription_t::type_name[256]

Type name storage

type_name_len

size_t nros_subscription_t::type_name_len

Type name length
