Struct TimerPerformance 

pub struct TimerPerformance { /* private fields */ }

Completed instruction and memory-page measurements split by callback role.

Each interval covers the accepted ic-timers callback envelope: it starts before callback acceptance and ends after completion processing and any successor binding. It is not an exclusive measurement of consumer code. Start/end page reads bracket the instruction interval from outside.

Instruction summaries retain observation ordering and track actual overflow: an exactly reached u64::MAX is still exact. Use the summary’s checked mean() or aggregate saturation flags rather than inferring overflow from its clipped total. Event counters and page-sample counts remain conservatively saturated at their numeric cap.

A terminal DeclarationLifetime::RemoveWhenStopped callback can remove its declaration before this final record is retained; no timer then remains in the inventory to expose that sample.
