go-async

A dead simple type safe implementation of the async - await pattern in golang

But why?

because:

1. it can be done
2. it cut's down on channel boilerplate
3. it gives programmers coming from languages like Rust, TypeScript and C# a familiar interface for concurrent programming

How to install:

• go get https://github.com/F-bh/go-async
• it requires at least golang version 1.18 to use

What is included

• 1 type called "Future"
• 1 function to turn a given function into a "Future"
  • Async()
• 2 methods to await the result of a given "Future"
  • Await()
  • AwaitWithTimeout()

Examples

package examples

import (
	"github.com/F-bh/go-async"
	"time"
)

func example(){
	future := Futures.Async(func() string{
		time.Sleep(500)
		return "Hello World"
	})

	println(future.Await())

	futureTimeout := Futures.Async(func() string{
		time.Sleep(50000000)
		return "unused"
	})

	val, ok := futureTimeout.AwaitWithTimeout(500)
	if !ok{
		println("timed out")
	}else{
		println(*val)
	}
}
