API

flow.DeferMany(size, task)

Выполнить операцию в гуртине и вернуть буферизированный канал для чтения результата

  • size int — размер буфера
  • task func(ret flow.Stream) — задача/callback, которую надо выполнить
res := flow.Defer(3, func (ret flow.Stream) {
    ret <- "1"
    ret <- "2"
    ret <- "3"
});

fmt.Println("Result:", <-res)

flow.Defer(task)

Частный случай flow.DeferMany

res := flow.Defer(func (ret flow.Stream) {
    ret <- "logic"
});

fmt.Println("Result:", <-res)

flow.CreateWorkerPool(size, worker) *sync.WaitGroup

Создать пул воркеров

  • size int — количество воркеров
  • worker func() — воркер/функция
func main() {
    input := getInputChan();

    // Читаем канал в 15 потоков
    wg := flow.CreateWorkerPool(15, func () {
        for raw := range input {
            // Чтение канала
        }
    })

    wg.Wait()
}

flow.Go(queue ...) error

Последовательно выполнение тасков до первой ошибки

    err := flow.Go(
        func() (err error) {
            // Первая задача
            return;
        },

        func() (err error) {
            // Вторая задача
            return;
        },
    )

Types

  • IntChan chan int
  • StrChan chan string
  • Stream chan interface{}
