Using channel with a timeout interval

The software program that connects to resources can be set with timeouts. Channels are used for implementing timeouts. You can configure a channel with a timeout interval as follows:

//main package has examples shown// in Go Data Structures and algorithms bookpackage main// importing errors, log and time packagesimport (    "errors"    "log"    "time")// delayTimeOut methodfunc delayTimeOut(channel chan interface{}, timeOut time.Duration) (interface{}, error) {    log.Printf("delayTimeOut enter")    defer log.Printf("delayTimeOut exit")    var data interface{}    select {        case <-time.After(timeOut):        return nil, errors.New("delayTimeOut time out")        case data = <-channel:        return data, nil    }}//main methodfunc main() { channel ...
