Types

type ByteSize

type ByteSize float64

	KB ByteSize = 1 << (10 * iota)
	MB

)

func (ByteSize) String

func (b ByteSize) String() string

type PassThru

type PassThru struct {
	io.Reader
	// contains filtered or unexported fields
}

PassThru wraps an existing io.Reader.

It simply forwards the Read() call, while displaying the results from individual calls to it.

func (*PassThru) Read

func (pt *PassThru) Read(p []byte) (int, error)

Read 'overrides' the underlying io.Reader's Read method. This is the one that will be called by io.Copy(). We simply use it to keep track of byte counts and then forward the call.
