}

Optional-per-policy container for all 22 OMG-DDS-1.4 QoS policies.

An unset Option means: not listed in the XML → spec default on resolve. Reused as one container for all 6 entity types — DDS-XML 1.0 in principle allows all policies in all 6 containers; semantic filtering (e.g. that OwnershipStrength only makes sense on the writer) happens when materializing into WriterQos/ReaderQos (see Self::into_writer_qos / Self::into_reader_qos).

Implementations

impl EntityQos

pub fn merge(self, override_: &Self) -> Self

Merges override_ over self: each explicitly set policy in override_ overrides the one in self. The operation is not commutative — order: parent.merge(child) means “child wins where the child explicitly set a value”.

pub fn into_writer_qos(&self) -> WriterQos

Materializes a WriterQos from the policies set in the EntityQos. None entries are filled with the spec defaults from zerodds_qos::WriterQos::default().

Policies that make no sense for a writer (e.g. time_based_filter, reader_data_lifecycle) are deliberately ignored here — they are only materialized for ReaderQos.

pub fn into_reader_qos(&self) -> ReaderQos

Materializes a ReaderQos analogous to Self::into_writer_qos.

Trait Implementations

impl Clone for EntityQos

fn clone(&self) -> EntityQos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EntityQos

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

Formats the value using the given formatter.

impl Default for EntityQos

fn default() -> EntityQos

Returns the “default value” for a type.

impl Eq for EntityQos

impl PartialEq for EntityQos

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

Equality operator ==.

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

Inequality operator !=.
