Constants

const ZFSUB_SIZE = 41

ZFSUB_SIZE is the size of the ZFSUB struct.

Types

type Probe

type Probe struct{}

func (*Probe) Magic

func (p *Probe) Magic() []*magic.Magic

Magic returns the magic value for the filesystem.

func (*Probe) Name

func (p *Probe) Name() string

Name returns the name of the filesystem.

func (*Probe) Probe

func (p *Probe) Probe(r probe.Reader, _ magic.Magic) (*probe.Result, error)

Probe runs the further inspection and returns the result if successful.
