Functions

func After

func After(n int, fn interface{}) func(args ...interface{}) []reflect.Value

After creates a function that invokes func once it's called n or more times

func Before

func Before(n int, fn interface{}) func(args ...interface{}) []reflect.Value

Before creates a function that invokes func once it's called less than n times

func Compose

func Compose(fnList ...func(...interface{}) interface{}) func(...interface{}) interface{}

Compose compose the functions from right to left

func Debounced

func Debounced(fn func(), duration time.Duration) func()

Debounced creates a debounced function that delays invoking fn until after wait duration have elapsed since the last time the debounced function was invoked.

func Delay

func Delay(delay time.Duration, fn interface{}, args ...interface{})

Delay make the function execution after delayed time

func Schedule

func Schedule(d time.Duration, fn interface{}, args ...interface{}) chan bool

Schedule invoke function every duration time, util close the returned bool chan

Types

type Fn

type Fn func(...interface{}) interface{}

Fn is for curry function which is func(...interface{}) interface{}

func (Fn) Curry

func (f Fn) Curry(i interface{}) func(...interface{}) interface{}

Curry make a curry function

type Watcher

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

Watcher is used for record code excution time

func (*Watcher) GetElapsedTime

func (w *Watcher) GetElapsedTime() time.Duration

GetElapsedTime get excute elapsed time.

func (*Watcher) Reset

func (w *Watcher) Reset()

Reset the watch timer.

func (*Watcher) Start

func (w *Watcher) Start()

Start the watch timer.

func (*Watcher) Stop

func (w *Watcher) Stop()

Stop the watch timer.
