Function Documentation

inline int64_t mosaic::elapsed_ns() noexcept

Nanoseconds elapsed since the first call to any elapsed_* function (effectively since application start).

Use this for durations and inter-event intervals — in particular for stamping video frames and trigger events, which must be aligned to each other. This clock never jumps backwards.

Returns:

Nanoseconds elapsed (always non-negative, starts near 0).
