Golang NewRunLengthEncoder Examples

Example #1

File: rle_test.go Project: CaptainIlu/cloud-torrent

func ExampleNewRunLengthEncoder() {
	var s string
	rle := missinggo.NewRunLengthEncoder(func(e interface{}, count uint64) {
		s += fmt.Sprintf("%d%c", count, e)
	})
	for _, e := range "WWWWWWWWWWWWBWWWWWWWWWWWWBBBWWWWWWWWWWWWWWWWWWWWWWWWBWWWWWWWWWWWWWW" {
		rle.Append(e, 1)
	}
	rle.Flush()
	fmt.Println(s)
	// Output: 12W1B12W3B24W1B14W
}

Example #2

File: torrent.go Project: soul9/torrent

func (t *torrent) pieceStateRuns() (ret []PieceStateRun) {
	rle := missinggo.NewRunLengthEncoder(func(el interface{}, count uint64) {
		ret = append(ret, PieceStateRun{
			PieceState: el.(PieceState),
			Length:     int(count),
		})
	})
	for index := range t.Pieces {
		rle.Append(t.pieceState(index), 1)
	}
	rle.Flush()
	return
