Introduction

Build Status codecov Go Report Card GoDoc

conexec is a concurrent toolkit to help execute functions concurrently in an efficient and safe way. It supports specifying the overall timeout to avoid blocking.

How to use

Generally it can be set as a singleton to save memory. There are some example to use it.

Normal Actuator

Actuator is a base struct to execute functions concurrently.

    opt := &Options{TimeOut:DurationPtr(time.Millisecond*50)}
    c := NewActuator(opt)

    err := c.Exec(
        func() error {
            fmt.Println(1)
            time.Sleep(time.Second * 2)
            return nil
        },
        func() error {
            fmt.Println(2)
            return nil
        },
        func() error {
            time.Sleep(time.Second * 1)
            fmt.Println(3)
            return nil
        },
    )

    if err != nil {
        // ...do sth
    }

Pooled Actuator

Pooled actuator uses the goroutine pool to execute functions. In some times it is a more efficient way.

    opt := &Options{TimeOut:DurationPtr(time.Millisecond*50)}
    c := NewPooledActuator(5, opt)

    err := c.Exec(...)

    if err != nil {
        // ...do sth
    }

Use custom goroutine pool

    c := NewPooledActuator(5).WithPool(pool)

Simply exec using goroutine

    done := Exec(...)

    if !done {
        // ... do sth 
    }
