Variables ¶

var (
	BLOCKSIZE int64 = 0x200

	// ErrNotAPartition is returned when a data block is not a valid partition type.
	ErrNotAPartition = errors.New("data block is not a valid partition type")
)

type Partition ¶

type Partition struct {
	Name string

	Base int64

	Size int64 // Size in blocks
}

Partition struct to hold partition information

func NewPartitionFromBytes ¶

func NewPartitionFromBytes(data []byte) (*Partition, error)

NewPartitionFromBytes acts as a constructor, parsing a partition from a byte slice.

func (*Partition) Extract ¶

func (p *Partition) Extract(srcFile *os.File, outputDir string) error

Extract saves the partition's data from the source file to a new file in the output directory.

func (*Partition) String ¶

func (p *Partition) String() string

String provides a human-readable summary of the partition, satisfying the fmt.Stringer interface.
