Functions

func DownloadFile

func DownloadFile(filePath string, url string) error

DownloadFile will download a url to a local file. It's efficient because it will write as it downloads and not load the whole file into memory. We pass an io.TeeReader into Copy() to report progress on the download.

func Execute

func Execute()

Types

type WriteCounter

type WriteCounter struct {
	Total uint64
}

https://golangcode.com/download-a-file-with-progress/ WriteCounter counts the number of bytes written to it. It implements to the io.Writer interface and we can pass this into io.TeeReader() which will report progress on each write cycle.

func (WriteCounter) PrintProgress

func (wc WriteCounter) PrintProgress()

func (*WriteCounter) Write

func (wc *WriteCounter) Write(p []byte) (int, error)
