QoS set for a DataReader — Spec §2.2.2.5.2.

Fields

reliability: ReliabilityQosPolicy

Reliability — reader default BestEffort (Spec §2.2.3.14.3).

durability: DurabilityQosPolicy

Durability — default Volatile.

deadline: DeadlineQosPolicy

Deadline — default INFINITE.

latency_budget: LatencyBudgetQosPolicy

LatencyBudget — hint, no match effect.

liveliness: LivelinessQosPolicy

Liveliness — default Automatic / INFINITE.

destination_order: DestinationOrderQosPolicy

DestinationOrder — default ByReceptionTimestamp.

ownership: OwnershipQosPolicy

Ownership — default Shared.

partition: PartitionQosPolicy

Partition — default empty.

presentation: PresentationQosPolicy

Presentation.

history: HistoryQosPolicy

History — default KeepLast(1).

resource_limits: ResourceLimitsQosPolicy

Resource limits.

time_based_filter: TimeBasedFilterQosPolicy

TimeBasedFilter — minimum_separation per instance.

reader_data_lifecycle: ReaderDataLifecycleQosPolicy

ReaderDataLifecycle — autopurge delays.

user_data: UserDataQosPolicy

UserData (propagated via discovery).

topic_data: TopicDataQosPolicy

TopicData (propagated via discovery).

group_data: GroupDataQosPolicy

GroupData (propagated via discovery).

data_representation: Option<Vec<i16>>

DataRepresentation (XTypes 1.3 §7.6.3.1.2): the accepted representation list (XCDR=0, XCDR2=2). None = runtime default. Per-reader override so that a reader specifically matches XCDR1 writers (ROS/RTI shapes) ([XCDR1, XCDR2]) without a global default.

Trait Implementations

impl Clone for DataReaderQos

fn clone(&self) -> DataReaderQos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataReaderQos

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

Formats the value using the given formatter.

impl Default for DataReaderQos

fn default() -> DataReaderQos

Returns the “default value” for a type.

impl Eq for DataReaderQos

impl From<ReaderQos> for DataReaderQos

Materializes a DDS-XML-resolved zerodds_qos::ReaderQos into the DCPS DataReaderQos. See From<zerodds_qos::WriterQos> for the writer side.

fn from(r: ReaderQos) -> DataReaderQos

Converts to this type from the input type.

impl PartialEq for DataReaderQos

fn eq(&self, other: &DataReaderQos) -> 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.
