Yet Another Worker Pool

YAWP is implementation worker pool with generic.

Design for not think about:

• result type
• error handling
• goroutine leaks
• panic handling

Questions

Pub, Run return Result type. Is it promise?

Yep, it's promise. Method Get lock until result is not ready.

If you need get result only than it's ready use RedirectOutput option.

Hot to install

go get github.com/popoffvg/Yet-Another-Worker-Pool

Usage

Use pool with function stream

wp := New[int, int](3)

for i := 0; i < 1_000; i++ {
    number := i + 1
    wp.Run(func(ctx context.Context) (int, error) {
        return number, nil
    })
}

Use pool with value stream

wp := New(3,
    WithWorker(func(ctx context.Context, i int) (int, error) {
        return i + 1, nil
    }),
)

for i := 0; i < 1_000; i++ {
    wp.Pub(number)
}

Use Pool Fun-In Fun-Out

wp := New(3, RedirectOutput[int, int]())
go func(){
    for {
        wp.Run(func(ctx context.Context) (int, error) {
            return 1, nil
        })
    }
}()

for v := range wp.Stream() {
   // get result as value stream
}
