Types

type ByteMap

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

func NewByteMap

func NewByteMap(Len int) *ByteMap

func (*ByteMap) Bytes

func (m *ByteMap) Bytes() []byte

func (*ByteMap) Fill

func (m *ByteMap) Fill(offset int, content []byte)

Fill without check if filled if content is too large ByteMap will be resized to fit in

func (*ByteMap) FillLeftWithNoise

func (m *ByteMap) FillLeftWithNoise(noise func() byte)

FillLeftWithNoise fill the left empty space with noise

func (*ByteMap) FindFree

func (m *ByteMap) FindFree(Len int) int

FindFree find the first free space with Len

func (*ByteMap) FindFreeAfter

func (m *ByteMap) FindFreeAfter(Len int, offset int) int

FindFreeAfter find the first free space with Len after offset

func (*ByteMap) FindFreeRange

func (m *ByteMap) FindFreeRange(Len, begin, end int) []int

FindFreeRange find all free spaces with Len in range [begin,end)

func (*ByteMap) Last

func (m *ByteMap) Last() (int, int)

Last is lastpos and lastLen
