Detailed Description

Metrics produced by a single QUIC stream over one sample period.

Unlike the connection's, these are taken away from the stream at each sample rather than read from it, so every value describes the period alone and a consumer adds successive samples to build a total.

Member Function Documentation

◆ Merge()

void quicr::QuicStreamMetrics::Merge ( const QuicStreamMetrics & other )

inline

Fold another stream's metrics into this one.

A flow may be carried by several streams at once, so its sample is the sum over the streams carrying it.

Parameters

other Period metrics to add to this object.

◆ operator<=>()

constexpr auto quicr::QuicStreamMetrics::operator<=> ( const QuicStreamMetrics & other ) const

constexprdefault

Compare all metric fields.

Parameters

other Metrics to compare.

Returns: Lexicographic comparison of the metric fields.
