Struct QosOverride 

pub struct QosOverride {
    pub topic: &'static str,
    pub role: QosOverrideRole,
    pub value: QosOverrideValue,
}

Phase 211.H — one per-topic QoS override, lowered from a ROS 2 qos_overrides.<topic>.<role>.<policy> launch parameter by the planner and baked into a &'static [QosOverride] table by the entry codegen. The node folds the matching entries into the entity’s QosSettings at create_publisher / create_subscription time (setup-time, single linear scan, no alloc), before the backend-compat validate_against — so an override the active RMW can’t honour still errors loudly, never a silent downgrade.

Fields

topic: &'static str

The resolved (remapped) topic name the override targets, e.g. "/chatter". Matched exactly against the entity’s topic.

role: QosOverrideRole

Publisher or subscription side.

value: QosOverrideValue

The policy + value to set.

Trait Implementations

impl Clone for QosOverride

fn clone(&self) -> QosOverride

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QosOverride

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

Formats the value using the given formatter.

impl PartialEq for QosOverride

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