Members

Variables

faultHandlersEnabled bool faultHandlersEnabled;: Whether to enable fault handlers
fiberStackSize size_t fiberStackSize;: Stack size of each fiber (except the main fiber). The reactor will allocate numFiber*fiberStackSize during startup
gcInterval Duration gcInterval;: How often does the GC's collection run.
gcRunThreshold size_t gcRunThreshold;: Allocation threshold to trigger a GC run
hangDetectorTimeout Duration hangDetectorTimeout;: Hard hang detection.
hoggerWarningThreshold Duration hoggerWarningThreshold;: Hogger detection threshold.
maxDesiredRunTime Duration maxDesiredRunTime;: Maximum desired fiber run time
numFibers ushort numFibers;: Maximum number of fibers.
numThreadsInPool uint numThreadsInPool;: Number of threads servicing deferred tasks
numTimers size_t numTimers;: Maximal number of timers that can be simultaneously registered.
registerDefaultIdler bool registerDefaultIdler;: Whether the reactor should register the default (fd processing) idle handler
threadDeferralEnabled bool threadDeferralEnabled;: Whether we have enabled deferToThread
threadStackSize size_t threadStackSize;: Worker thread stack size
timerGranularity Duration timerGranularity;: Base granularity of the reactor's timer.
utGcDisabled bool utGcDisabled;: Disable all GC collection during the reactor run time. Only available for UTs.
