Crate oa_gateway_dds

DDS adapter. Samples are A-GRA Rx/Tx; streams are DDS topic names.

The adapter talks to a DdsProvider. This build ships RustddsProvider. A later vendor stack is another type behind the same trait. QoS comes from a file the provider interprets.

Engine topic equals DDS topic. The engine sees envelopes only.

Modules

• adapter 🔒
  Bridges configured engine topics onto DDS topics of the same name.
• config 🔒
  Runtime settings for a DDS session. This is not the host TOML section.
• convert 🔒
  UCI schema-violation check for inbound DDS samples.
• provider 🔒
  Provider shim. The adapter talks only to these traits.
• qos_xml 🔒
  Documented DDS-XML subset used by the rustdds provider.
• types 🔒
  On-wire sample for rustdds: one type that carries either Rx or Tx.

Structs

• DdsAdapter
  DDS participant that bridges configured topics both ways.
• DdsConfig
  Runtime settings for a DDS session.
• DdsSample
  Provider-neutral sample the adapter reads and writes.
• MaDataPayload
  rustdds / CDR representation of DdsSample.
• QosSpec
  Reliability, durability, and history taken from one QoS profile.
• RustddsProvider
  First provider. QoS XML is parsed by crate::load_qos.

Enums

• DdsError
  Failure inside a provider. The adapter maps this onto oa_gateway_adapter::AdapterError.
• DdsProviderKind
  Which crate::DdsProvider the host should construct.

Constants

• DEFAULT_MAX_SAMPLE_SIZE
  Largest DDS sample accepted from the domain, in bytes, before it is unwrapped or converted.
• TYPE_NAME
  Type name passed to create_topic.

Traits

• DdsProvider
  Joins a domain and returns a session.
• DdsSession
  One participant: topics, writes, and inbound samples.

Functions

• load_qos
  Reads QosSpec from path.
• parse_qos
  Parses the subset from xml.
• provider_for
  Builds the provider named by kind.
