Types

type Operation

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

func Begin

func Begin(logger *log.Logger, dev string) *Operation

Begin begins an sgdisk operation

func (*Operation) Commit

func (op *Operation) Commit() error

Commit commits an partitioning operation.

func (*Operation) CreatePartition

func (op *Operation) CreatePartition(p Partition)

CreatePartition adds the supplied partition to the list of partitions to be created as part of an operation.

func (*Operation) DeletePartition

func (op *Operation) DeletePartition(num int)

func (*Operation) Info

func (op *Operation) Info(num int)

func (*Operation) Pretend

func (op *Operation) Pretend() (string, error)

Pretend is like Commit() but uses the --pretend flag and returns the output on stdout for parsing.

Note: because sgdisk does not do any escaping on its output, callers should ensure the partitions' labels do not have any nasty characters that will interfere with parsing (e.g. \n)

func (*Operation) WipeTable

func (op *Operation) WipeTable(wipe bool)

WipeTable toggles if the table is to be wiped first when commiting this operation.

type Partition

type Partition struct {
	types.Partition
	StartSector   *int64
	SizeInSectors *int64

	// shadow StartMiB/SizeMiB so they're not accidentally used
	StartMiB string
	SizeMiB  string
}

We ignore types.Partition.StartMiB/SizeMiB in favor of StartSector/SizeInSectors. The caller is expected to do the conversion.
