Detailed Description

Service server structure.

Field Documentation

◆ _internal

struct ServiceServerInternal nros_service_t::_internal

Internal state (arena entry index + executor pointer). Phase 87.5: Typed C-ABI handle field (was an opaque blob in earlier versions).

◆ _opaque

uint64_t nros_service_t::_opaque[SERVICE_SERVER_OPAQUE_U64S]

Phase 122.3.c.4 — inline opaque storage for the L1 polling-mode RawServiceServer<MESSAGE_BUFFER_SIZE, MESSAGE_BUFFER_SIZE>. Zeroed in L2 (callback + executor arena) mode; populated by nros_service_init_polling.

◆ callback

nros_service_callback_t nros_service_t::callback

User callback function

◆ context

void* nros_service_t::context

User context pointer

◆ node

const struct nros_node_t* nros_service_t::node

Pointer to parent node

◆ qos

struct nros_qos_t nros_service_t::qos

Phase 193.4 — service QoS (applied to both request + reply endpoints). Defaults to the services profile (RELIABLE+VOLATILE+KEEP_LAST(10)); set via nros_service_init_with_qos.

◆ sched_context_id

nros_sched_context_id_t nros_service_t::sched_context_id

Phase 189.M3.3.a — scheduling-context slot to bind the service's executor handle to. 0 = inherit the executor / Node default (no explicit bind); set via nros_service_init_with_options. When non-zero, nros_executor_register_service binds the freshly-created handle to this SC after registration. No effect on the L1 polling path.

◆ service_name

uint8_t nros_service_t::service_name[256]

Service name storage

◆ service_name_len

size_t nros_service_t::service_name_len

Service name length

◆ state

enum nros_service_state_t nros_service_t::state

Current state

◆ type_hash

uint8_t nros_service_t::type_hash[128]

Type hash storage

◆ type_hash_len

size_t nros_service_t::type_hash_len

Type hash length

◆ type_name

uint8_t nros_service_t::type_name[256]

Type name storage

◆ type_name_len

size_t nros_service_t::type_name_len

Type name length
