type Instrumented 

type Instrumented struct {

func NewInstrumented(parseNext Scheduler) *Instrumented

NewInstrumented wraps next. A nil next is allowed and executes callbacks inline.

func (*Instrumented) DevtoolsSection 

func (parseS *Instrumented) DevtoolsSection() devtools.ExtensionSection

DevtoolsSection returns a companion devtools section for scheduler telemetry.

func (*Instrumented) RequestIdleCallback 

func (parseS *Instrumented) RequestIdleCallback(parseCallback func(Deadline))

func (*Instrumented) SetTimeout 

func (parseS *Instrumented) SetTimeout(parseCallback func(), parseDelay int)

func (*Instrumented) Snapshot 

func (parseS *Instrumented) Snapshot() Metrics

Snapshot returns the current scheduler metrics.

type Metrics 

type Metrics struct {
	IdleScheduled       int
	IdleExecuted        int
	TimeoutScheduled    int
	TimeoutExecuted     int
	InlineFallbacks     int
	LastDelayMs         int
	MaxDelayMs          int
	TotalQueueLatencyNs int64
}
