rmw_service_t

Struct rmw_service_t 

Source
#[repr(C)]
pub struct rmw_service_t { pub service_name: *const c_char, pub type_name: *const c_char, pub _reserved: [u8; 8], pub backend_data: *mut c_void, }
Expand description

Service entity (phase-301: renamed from service_server to the upstream rmw_service_t term).

Service entities have no QoS in the nros subset (the upstream rmw_qos_profile_services_default distinction does not generalise across non-DDS backends — see book concepts/ros2-comparison.md).

No can_loan_messages field — service request/reply currently always goes through take_request / send_response byte-buffer APIs. If a future backend wants service-side lending, the _reserved[8] block accommodates the bool + 7 padding bytes without an ABI break.

Fields§

§service_name: *const c_char

Service name (borrowed; outlives the server).

§type_name: *const c_char

Fully-qualified service type name (e.g., "example_interfaces/srv/AddTwoInts"). Borrowed.

§_reserved: [u8; 8]

Reserved for future fields; must be zero.

§backend_data: *mut c_void

Opaque backend state. NULL if creation failed.
