Types

type LogicalBlockAddresser

type LogicalBlockAddresser struct {
	PhysicalBlockSize uint64
	LogicalBlockSize  uint64
}

LogicalBlockAddresser represents Logical Block Addressing.

func New

func New(f *os.File) (lba *LogicalBlockAddresser, err error)

New initializes and returns a LogicalBlockAddresser.

func (*LogicalBlockAddresser) Copy

func (lba *LogicalBlockAddresser) Copy(dst []byte, src []byte, rng Range) (int, error)

Copy copies from src to dst in the specified range.

func (*LogicalBlockAddresser) From

func (lba *LogicalBlockAddresser) From(src []byte, rng Range) ([]byte, error)

From returns a slice from a source slice in the the specified range inclusively.

func (*LogicalBlockAddresser) Make

func (lba *LogicalBlockAddresser) Make(size uint64) []byte

Make returns a slice from a source slice in the the specified range inclusively.

type Range

type Range struct {
	Start uint64
	End   uint64
}

Range represents a range of Logical Block Addresses.
