goreturn

goreturn is a Go library that provides a set of functions to run a function in a goroutine and return its result(s) in a channel. This library is designed to make it easier to work with goroutines and channels in Go, especially when dealing with functions that return multiple values.

Features

• Return0(fn func()) <-chan any: Runs a function with no return values in a goroutine and returns a channel that will receive a single nil value when the function completes.
• Return1[T1 any](fn func() T1) <-chan T1: Runs a function with one return value in a goroutine and returns a channel that will receive the return value.
• Return2[T1 any, T2 any](fn func() (T1, T2)) <-chan *Tuple[T1, T2]: Runs a function with two return values in a goroutine and returns a channel that will receive a tuple containing the return values.
• Return3[T1 any, T2 any, T3 any](fn func() (T1, T2, T3)) <-chan *Tuple3[T1, T2, T3]: Runs a function with three return values in a goroutine and returns a channel that will receive a tuple containing the return values.

Installation

To install goreturn, use the go get command:

go get github.com/Eyal-Shalev/goreturn

Usage

Here is an example of how to use goreturn:

package main

import (
	"fmt"
	"github.com/Eyal-Shalev/goreturn"
)

func main() {
	c := goreturn.Return1(func() int {
		return 42
	})
	v := <-c
	fmt.Println("Return1() returned", v)
}

In this example, the function func() int { return 42 } is run in a goroutine, and its return value is received from the channel returned by Return1.
