	io.Reader
	io.Writer
	io.Seeker
	fs.File
	fs.ReadDirFile
}

type FileSystem

type FileSystem interface {
	// Stat returns a FileInfo describing the named file.
	// If there is an error, it will be of type *PathError.
	Stat(name string) (fs.FileInfo, error)
	// OpenFile is the generalized open call; most users will use Open
	// or Create instead. It opens the named file with specified flag
	// (O_RDONLY etc.). If the file does not exist, and the O_CREATE flag
	// is passed, it is created with mode perm (before umask). If successful,
	// methods on the returned File can be used for I/O.
	// If there is an error, it will be of type *PathError.
	OpenFile(name string, flag int, perm fs.FileMode) (File, error)
	// Mkdir creates a new directory with the specified name and permission
	// bits (before umask).
	// If there is an error, it will be of type *PathError.
	Mkdir(name string, perm fs.FileMode) error
	// Remove removes the named file or (empty) directory.
	// If there is an error, it will be of type *PathError.
	Remove(name string) error
}
