}

Full DDS-shaped QoS profile. Mirrors nros_rmw_qos_t from <nros/rmw_entity.h>.

Fields

reliability: u8

Reliability policy: 0 = best-effort, 1 = reliable.

durability: u8

Durability policy: 0 = volatile, 1 = transient-local.

history: u8

History policy: 0 = keep-last, 1 = keep-all.

liveliness_kind: u8

Liveliness kind. See NrosRmwLivelinessKind.

depth: u16

History depth (0–65 535).

_reserved0: u16

Reserved; must be zero.

deadline_ms: u32

Subscriber max-inter-arrival / publisher offered-rate, ms. 0 = infinite (no deadline).

lifespan_ms: u32

Sample expiry, ms. 0 = infinite.

liveliness_lease_ms: u32

Liveliness lease, ms. 0 = infinite.

avoid_ros_namespace_conventions: u8

If non-zero, topic name encoding skips the ROS /rt/ prefix. u8 instead of bool for ABI parity with C — sizeof(_Bool) is impl-defined per C99.

_reserved1: [u8; 3]

Reserved; must be zero.

rx_buffer_hint: u32

Phase 231 (RFC-0038) — subscription receive-buffer size hint, bytes. Carries TopicInfo::rx_buffer_hint across the C ABI to create_subscriber so a size-classing backend (zenoh-pico) can pick a small/large receive buffer. 0 = unset. Appended at the struct tail (ABI-append); ignored by every slot except create_subscriber.

Trait Implementations

impl Clone for NrosRmwQos

fn clone(&self) -> NrosRmwQos

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for NrosRmwQos

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<QosSettings> for NrosRmwQos

fn from(qos: QosSettings) -> Self

Converts to this type from the input type.

impl PartialEq for NrosRmwQos

fn eq(&self, other: &NrosRmwQos) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
