详细描述

Statistics and metadata for a single discovered topic endpoint.

Delivered in batches via InfoCallback once per second. The fields freq, rate, loss, and latency are weighted moving averages computed over the last two 1-second collection intervals.

类成员变量说明

freq

float vlink::ProxyAPI::Info::freq {0}

Observed message frequency in messages/s.

latency

float vlink::ProxyAPI::Info::latency {0}

End-to-end latency in milliseconds.

loss

float vlink::ProxyAPI::Info::loss {0}

Sample loss ratio in the range [0, 1].

process_list

std::vector<Process> vlink::ProxyAPI::Info::process_list

List of connected publisher/subscriber processes.

rate

uint64_t vlink::ProxyAPI::Info::rate {0}

Observed throughput in bytes/s.

schema

SchemaType vlink::ProxyAPI::Info::schema {SchemaType::kUnknown}

Coarse schema family of the payload.

ser

std::string vlink::ProxyAPI::Info::ser

Serialisation type, e.g. "demo.proto.PointCloud".

status

Status vlink::ProxyAPI::Info::status {kInvalid}

Activity status of the topic.

type

uint32_t vlink::ProxyAPI::Info::type {0}

Node type bitmask for this endpoint.

url

std::string vlink::ProxyAPI::Info::url

Full topic URL, e.g. "dds://my/topic".
