FrameSample

Kind	typedef
Package	debug
Full name	debug.FrameSample
Source	source/debug/FrameProfiler.hx

Per-frame sample snapshot captured by the Phoenix Engine frame profiler.

Units & Semantics:

• All durations are in milliseconds.
• Exclusive durations (updateTimeMs, renderTimeMs, audioTimeMs, gcPauseMs): Nested child phase durations are subtracted from their enclosing parent phase via an explicit LIFO phase stack (phaseStack).
• Inclusive durations (updateInclusiveMs, renderInclusiveMs, audioInclusiveMs, gcInclusiveMs): Total time spent inside the outermost activation(s) of each phase, including nested child phases.
• gcPauseMs and gcCount/explicitGcCount reflect directly measured GC pauses.
• implicitGcCount counts observed negative heap-delta intervals outside explicit GC scopes (heuristic indicator of uninstrumented collection, not an exact cycle count).
• rssSampled is true when process RSS was freshly sampled on this frame and false when carried forward from the previous periodic RSS sample.
