structTimerState

Windows performance-counter-based timer state.

Wraps QueryPerformanceCounter/QueryPerformanceFrequency to provide millisecond-precision timing for the event loop timer wheel.

Fields

long _perfFreq

long _startTime

Methods

bool initialize(ref TimerWheel timerWheel) @trusted nothrowInitialize the timer state by calibrating the performance counter.

long currentTimeMs() @trusted nothrow @nogcGet the current time in milliseconds since initialization.

int computePollTimeout(Slot)(int  requestedTimeoutMs,
          const  ref  TimerWheel timerWheel,
          scope  const(Slot)[]  slots)

const pure @safe nothrow @nogcCompute the poll timeout considering timer deadlines and idle watchers.

long perfFreq() const pure @safe nothrow @nogc
