详细描述

Statistics and metadata describing one discovered topic endpoint.

Delivered in batches through InfoCallback once per second. freq, rate, loss, and latency are weighted moving averages over the last two one-second collection intervals.

类成员变量说明

freq

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

Observed message rate in messages/s.

latency

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

Latency in ms; -1 = no sample, -2 = invalid.

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

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}

Current 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".
