Aggregate Quality of Service policy for a VLink communication endpoint.
All sub-policies have sensible defaults. Only the fields relevant to the active transport backend are used; unsupported fields are silently ignored.
The name field (max 19 chars) identifies the profile for display purposes. The valid flag must be true for the Qos to be applied; QosProfile constants already set valid = true.
| Additions vlink::Qos::additions |
VLink-specific extensions.
| Deadline vlink::Qos::deadline |
Maximum period between publications.
| DestinationOrder vlink::Qos::destination_order |
Sample ordering policy.
| Durability vlink::Qos::durability |
Sample persistence policy.
| History vlink::Qos::history |
Sample retention policy.
| LatencyBudget vlink::Qos::latency_budget |
Acceptable end-to-end latency hint.
| Lifespan vlink::Qos::lifespan |
Maximum sample age before discard.
| Liveliness vlink::Qos::liveliness |
Liveliness assertion policy.
| char vlink::Qos::name[20] = {0} |
Profile name (max 19 chars + NUL). For display only.
| Ownership vlink::Qos::ownership |
Writer ownership policy.
| PublishMode vlink::Qos::publish_mode |
Synchronous or asynchronous publishing.
| Reliability vlink::Qos::reliability |
Delivery guarantee policy.
| ResourceLimits vlink::Qos::resource_limits |
Internal queue size limits.
| bool vlink::Qos::valid {false} |
Must be true for the Qos to be applied by the transport.
