Functions

func ParseCaller

func ParseCaller(funcName string) (string, string)

ParseCaller returns the package based function name from the runtime based function call name

Types

type Call

type Call struct {
	PkgName  string
	FuncName string
}

Call represents the package of the calling position and the function of the calling position

type Data

type Data struct {
	CallCount int64
	TSum      int64
	TMin      int64
	TMax      int64
}

Data represents statistics data of the instance

type Instance

type Instance struct {
	// contains filtered or unexported fields
}

Instance represents profiler of the goroutine

func Enter

func Enter() *Instance

Enter returns the profiler of the current function in the current goroutine

func EnterTag

func EnterTag(Tag string) *Instance

EnterTag returns the profiler of the current function in the current goroutine with the tag

func (*Instance) Exit

func (pi *Instance) Exit()

Exit apply the estimation time of the instance of the profiler

type Profiler

type Profiler struct {
	sync.RWMutex
	Caller    string
	FileName  string
	Line      int
	GOID      int64
	ParentMap map[string]bool
	// contains filtered or unexported fields
}

Profiler is an alpha stage (*unstable yet) It provides profile functions regardless of goroutines

func (*Profiler) Exit

func (p *Profiler) Exit(Tag string, tLastEnter int64)

Exit apply the estimation time of the instance of the profiler with the tag

func (*Profiler) ID

func (p *Profiler) ID() string

ID returns the unique ID of the profiler

type SnapshotData

type SnapshotData struct {
	ID       string
	PkgName  string
	FuncName string
	FileName string
	Line     int
	Parents  []*Call
	Tag      string
	Data     Data
	TDiff    int64
}

SnapshotData represents the profile data of the profiler instance

func Snapshot

func Snapshot() []SnapshotData

Snapshot returns all snapshots that are generated by all profiler instances

type Watcher

type Watcher struct {
	C chan SnapshotData
}

Watcher is an alpha stage (*unstable yet) It provides a subscription channel of the profiler

func Watch

func Watch() *Watcher

Watch returns a subscription channel of the profiler
