Types

type Option

type Option func(*Options)

Option is the functional option func.

func WithLegacyBIOSBootableAttribute

func WithLegacyBIOSBootableAttribute(o bool) Option

WithLegacyBIOSBootableAttribute marks the partition as bootable.

func WithPartitionName

func WithPartitionName(o string) Option

WithPartitionName sets the partition name.

func WithPartitionTest

func WithPartitionTest(t bool) Option

WithPartitionTest allows us to disable the IsNew partition check. This is only intended to be used for tests.

func WithPartitionType

func WithPartitionType(id string) Option

WithPartitionType sets the partition type.

type Options

type Options struct {
	Type  uuid.UUID
	Name  string
	Flags uint64
	Test  bool
}

Options is the functional options struct.

func NewDefaultOptions

func NewDefaultOptions(setters ...interface{}) *Options

NewDefaultOptions initializes a Options struct with default values.

type Partition

type Partition struct {
	Type          uuid.UUID // 0
	ID            uuid.UUID // 16
	FirstLBA      uint64    // 32
	LastLBA       uint64    // 40
	Flags         uint64    // 48
	Name          string    // 56
	TrailingBytes []byte    // 128

	Number int32

	IsNew     bool
	IsResized bool
	// contains filtered or unexported fields
}

Partition represents a partition entry in a GUID partition table.

func NewPartition

func NewPartition(data []byte) *Partition

NewPartition initializes and returns a new partition.

func (*Partition) Bytes

func (prt *Partition) Bytes() []byte

Bytes returns the partition as a byte slice.

func (*Partition) Fields

func (prt *Partition) Fields() []*serde.Field

Fields implements the serder.Serde interface.

func (*Partition) Length

func (prt *Partition) Length() int64

Length returns the partition's length in LBA.

func (*Partition) No

func (prt *Partition) No() int32

No returns the partition's number.

func (*Partition) Start

func (prt *Partition) Start() int64

Start returns the partition's starting LBA..
