func (*VSSFS) Symlink

func (fs *VSSFS) Symlink(target, link string) error

func (*VSSFS) TempFile

func (fs *VSSFS) TempFile(dir, prefix string) (billy.File, error)

type VSSFileInfo

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

func (*VSSFileInfo) IsDir

func (fi *VSSFileInfo) IsDir() bool

func (*VSSFileInfo) ModTime

func (fi *VSSFileInfo) ModTime() time.Time

func (*VSSFileInfo) Mode

func (fi *VSSFileInfo) Mode() fs.FileMode

func (*VSSFileInfo) Name

func (fi *VSSFileInfo) Name() string

func (*VSSFileInfo) Size

func (fi *VSSFileInfo) Size() int64

func (*VSSFileInfo) Sys

func (vi *VSSFileInfo) Sys() interface{}

type VSSIDHandler

type VSSIDHandler struct {
	nfs.Handler
	// contains filtered or unexported fields
}

VSSIDHandler uses VSSFS's PathToID and IDToPath for handle management.

func NewVSSIDHandler

func NewVSSIDHandler(vssFS *VSSFS, underlyingHandler nfs.Handler) *VSSIDHandler

NewVSSIDHandler initializes the handler with a reference to VSSFS.

func (*VSSIDHandler) FromHandle

func (h *VSSIDHandler) FromHandle(handle []byte) (billy.Filesystem, []string, error)

func (*VSSIDHandler) HandleLimit

func (h *VSSIDHandler) HandleLimit() int

HandleLimit returns the number of precomputed handles.

func (*VSSIDHandler) InvalidateHandle

func (h *VSSIDHandler) InvalidateHandle(fs billy.Filesystem, handle []byte) error

InvalidateHandle is a no-op as handles are immutable.

func (*VSSIDHandler) ToHandle

func (h *VSSIDHandler) ToHandle(f billy.Filesystem, path []string) []byte
