Struct ros2_client::DEFAULT_SUBSCRIPTION_QOS

pub struct DEFAULT_SUBSCRIPTION_QOS { /* private fields */ }

Basic BestEffort QoS for subscribers

Note: If you want Reliable communication, both publisher and Subscriber must specify QoS Reliability = Reliable.

Methods from Deref<Target = QosPolicies>

pub fn durability(&self) -> Option<Durability>

pub fn is_volatile(&self) -> bool

pub fn presentation(&self) -> Option<Presentation>

pub fn deadline(&self) -> Option<Deadline>

pub fn latency_budget(&self) -> Option<LatencyBudget>

pub fn ownership(&self) -> Option<Ownership>

pub fn liveliness(&self) -> Option<Liveliness>

pub fn time_based_filter(&self) -> Option<TimeBasedFilter>

pub fn reliability(&self) -> Option<Reliability>

pub fn is_reliable(&self) -> bool

pub fn reliable_max_blocking_time(&self) -> Option<Duration>

pub fn destination_order(&self) -> Option<DestinationOrder>

pub fn history(&self) -> Option<History>

pub fn resource_limits(&self) -> Option<ResourceLimits>

pub fn lifespan(&self) -> Option<Lifespan>

pub fn modify_by(&self, other: &QosPolicies) -> QosPolicies

Merge two QosPolicies

Constructs a QosPolicy, where each policy is taken from self, and overwritten with those policies from other that are defined.

pub fn compliance_failure_wrt(&self, other: &QosPolicies) -> Option<QosPolicyId>

Check if policy complies to another policy.

self is the “offered” (publisher) QoS other is the “requested” (subscriber) QoS

• None => Policies are compatible
• Some(policyId) => Failure, where policyId is (any) one of the policies causing incompliance

Compliance (compatibility) is defined in the table in DDS spec v1.4 Section “2.2.3 Supported QoS”

This is not symmetric.
