Types

type FS

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

FS implements a read-only meta file system where failing method calls to higher level file systems are passed to other file systems.

func New

func New(fsys fs.FS) *FS

New creates a new buffer FS.

func (*FS) Open

func (fsys *FS) Open(name string) (item fs.File, err error)

Open opens a file for reading.

type File

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

func (*File) Close

func (f *File) Close() (err error)

func (*File) Name

func (f *File) Name() string

func (*File) Read

func (f *File) Read(p []byte) (n int, err error)

func (*File) ReadAt

func (f *File) ReadAt(p []byte, off int64) (n int, err error)

func (*File) ReadDir

func (f *File) ReadDir(count int) (fi []fs.DirEntry, err error)

func (*File) Seek

func (f *File) Seek(offset int64, whence int) (int64, error)

func (*File) Stat

func (f *File) Stat() (fs.FileInfo, error)
