async-exec-go

async-exec-go is a generic function to manage asynchronous calls in go applications.

Install

go get -u github.com/kuckchuck96/async-exec-go

How does it work?

• Create your function with the below format or pattern.

func incrementAge(age int) int {
	return age + 3
}

Please note you function should only accept 2 input params i.e. param1 of any type.

• You can call above function using Executor as follows:

async.Executor(incrementAge, age, result, wg)

incrementAge is a function, age is input param, result is output channel, and wg is *sync.WaitGroup.

• Now you can use either Wait() in *sync.WaitGroup to wait for the completion of goroutines or Result(chan, time.Duration) recently introduced to wait for the requested channel for the set amount of duration.

data, err := Result(result, 6*time.Second)
if err != nil {
	fmt.Println("Err:", err)
} else {
	fmt.Println("Data:", data)
}
