syncerr

Alternative to errgroup.Group that is context-independent and returns all errors.

In some cases it may be desirable to run multiple tasks concurrently and inspect or log the error returned by each of them. This package provides an alternative to errgroup.Group that implements this alternate behavior.

Dependencies

The main module has no dependencies beside the Go standard library.

Usage

The main type provided by this package is Group. Its API is similar to errgroup.Group:

package main

import (
	"errors"
	
	"github.com/nulab/syncerr"
)

func main() {
	// You can initialize a new variable by just using `new`  
	g := new(syncerr.Group)
	
	// run tasks concurrently similarly to what you'd do with errgroup.Group
	g.Go(func() error {
		// do some task
		return errors.New("whoops!")
    })

	g.Go(func() error {
		// do some other task
		return errors.New("ouch!")
	})
	
	// wait for all tasks to complete
	g.Wait()
	
	// this error wraps all errors returned by the child tasks with errors.Join 
	err := g.Error()
	if err != nil {
		// handle error
    }
	// success!
}

Status

This project is actively under development, but it is currently in version 0. Please be aware that the public API and exported methods may undergo changes.
