to_history()

template<typename T >

Memory::HistoryBuffer< T > MayaFlux::Kinesis::to_history ( std::span< const T >  samples )

inlinenoexcept

Build a HistoryBuffer<T> from a newest-first span.

Template Parameters

T	Sample type

Parameters

samples

Span with samples[0] newest, samples[N-1] oldest

Returns

HistoryBuffer<T> of capacity samples.size() with matching contents

Exposed directly since several call sites below only need this step once before calling a HistoryBuffer<T>& overload repeatedly, e.g. comparing several difference orders against the same window without rebuilding it per call.
