Learning Functional Programming in Go

The decorator/requestor.go file

The DEBUG output leads us to our last go source file, namely requestor.go:

package decoratorimport (       "io"       "io/ioutil"       "net/http"       "os"       "os/signal"       "sync"       "syscall"       "time")type response struct {       duration      time.Duration       err           error}

The response struct is used to record the duration and any error from running our request. When we capitalize names of symbols, for example, the "J" in our struct named Job in the following code, we are telling Go to export it. When we import a package we will only be able to access exported symbols.

type Job struct {       Client       Client       NumRequests  int       Request      *http.Request       IntervalSecs int       responseChan chan *response}

The private field, responses, is a channel of response pointers with a ...
