Types ¶

type Reader ¶

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

Reader simulates a fake read-only file of an arbitrary size. The contents of this file cycles through the lowercase alphabetical ascii characters (abcdefghijklmnopqrstuvwxyz) Data is generated as requested, so it is safe to generate a 100GB file with 1GB of memory free on your machine.

func NewReader ¶

func NewReader(n int) *Reader

func (*Reader) Read ¶

func (r *Reader) Read(p []byte) (n int, err error)

Read reads lowercase ascii characters into b from f. n is number of bytes read. If a Read is attempted at the end of the file, io.EOF is returned.
