Overview

Package errgroup provides synchronization, error propagation, and Context cancelation for groups of goroutines working on subtasks of a common task. Based on golangorg/x/sync

Example (WithTags) 
package main

import (
	"fmt"
)

Functions

func Asset 

func Asset(err error)

func CombineError 

func CombineError(errs ...error) error

func CopyDir 

func CopyDir(src string, dst string) error

CopyDir copy directory from src to dst.

func CopyFile 

func CopyFile(src, dst string) error

CopyFile copy a single file.

func DecodeValue 

func DecodeValue(value []byte, dest interface{}) (err error)

DecodeValue decode value to dest.

func EncodeKey 

func EncodeKey(key interface{}) (res []byte, err error)

EncodeKey returns key in bytes.

func EncodeValue 

func EncodeValue(value interface{}) (res []byte, err error)

EncodeValue returns value in bytes.

func Exist 

func Exist(path string) bool

Exist check if the file with the given path exits.

func Exist2 

func Exist2(path string) bool

Exist check if the directory or file exists.

func Float64ToStr 

func Float64ToStr(val float64) string

func SelectError 

func SelectError(errs ...error) error

func StrToFloat64 

func StrToFloat64(val string) (float64, error)

func TraceError 

func TraceError(err error, skip int) error

Types

type Group 

type Group struct {
	// contains filtered or unexported fields
}

A Group is a collection of goroutines working on subtasks that are part of the same overall task.

A zero Group is valid and does not cancel on error.

func WithContext 

func WithContext(ctx context.Context) (*Group, context.Context)

WithContext returns a new Group and an associated Context derived from ctx.

The derived Context is canceled the first time a function passed to Go returns a non-nil error or the first time Wait returns, whichever occurs first.

func (*Group) Go 

func (g *Group) Go(f func() error)

Go calls the given function in a new goroutine.

The first call to return a non-nil error cancels the group; its error will be returned by Wait.

func (*Group) Wait 

func (g *Group) Wait() error

Wait blocks until all function calls from the Go method have returned, then returns an error representing all errors encountered from any goroutines in the group.
