parallelworker

this is a simple lib to do work parallel.

for example: you need do some check, called check A, check B, check C, and those check are not interdependent, so we can do those check at the same time

Usage

1. make a content

ctx := context.Background()

2. make worker

worker := parallelworker.NewParallelWorker(ctx)

3. add all your worker

worker.AddWorker(func(ctx context.Context) {
    select {
    	case <-ctx.Done():
            // if ctx is cancel, you should return your function
            return
        default:
    }
    // do something
})

4. wait for finish

   this function will be blocked, so you need add a timeout context to control it, this context is different from the first one

timeOutCtx := context.WithTimeout(ctx, time.Second * 5)
worker.WaitContext(timeOutCtx)
