Functions

func Cleanup

func Cleanup()

Cleanup deletes the local storage for the current go routine

func Delete

func Delete(key string)

Delete deletes a variable from the local storage of the current go routine

func Get

func Get(key string) (interface{}, bool)

Get returns a variable from the local storage of the current go routine

func Go

func Go(f func())

Go executes the given function in a go routine and ensures that the local storage is initialized before the function is called and deleted before after the function returns or panics

Example

Init()
var wg sync.WaitGroup
wg.Add(2)

Set(`key`, `main value`)
Go(func() {
	Set(`key`, `value 1`)
	Go(func() {
		Set(`key`, `value 2`)
		v, _ := Get(`key`)
		fmt.Printf("g2 = %s\n", v)
		Delete(`key`)
		wg.Done()
	})
	v, _ := Get(`key`)
	fmt.Printf("g1 = %s\n", v)
	Delete(`key`)
	wg.Done()
})
wg.Wait()
v, _ := Get(`key`)
fmt.Printf("main = %v\n", v)

Output:

g1 = value 1
g2 = value 2
main = main value

func Init

func Init()

Init initializes a go routine local storage for the current go routine

func Set

func Set(key string, value interface{})

Set adds or replaces a variable to the local storage of the current go routine
