Struct rmw_subscription_t 

#[repr(C)]
pub struct rmw_subscription_t {
    pub topic_name: *const c_char,
    pub type_name: *const c_char,
    pub qos: rmw_qos_profile_t,
    pub can_loan_messages: bool,
    pub _reserved: [u8; 7],
    pub backend_data: *mut c_void,
}

Subscription entity (phase-301: renamed from subscriber to the upstream rmw_subscription_t term). Same shape as the publisher; can_loan_messages means the backend exposes the receive-side loan primitive.

Fields

topic_name: *const c_char

Topic name (borrowed; outlives the subscription).

type_name: *const c_char

Fully-qualified type name. Borrowed.

qos: rmw_qos_profile_t

QoS subset honoured by this subscription.

can_loan_messages: bool

Backend exposes loan_recv / release_recv (Phase 99). DERIVED by the runtime from vtable->take_loaned_message; a backend’s write is overwritten (issue 0814).

_reserved: [u8; 7]

Reserved for future fields; must be zero.

backend_data: *mut c_void

Opaque backend state. NULL if creation failed.
