Functions

func Abs

func Abs(cwd, name string) string

Abs returns name if name is an absolute path. If name is a relative path then an absolute path is constructed by using cwd as the current working directory.

func PopPath

func PopPath(path string) (string, string)

PopPath returns the first name in `path` and the rest of the `path` string. The path provided must use forward slashes ("/").

Types

type DirEntry

type DirEntry struct {
	Name  string
	Inode *Inode
}

func (*DirEntry) IsDir

func (e *DirEntry) IsDir() bool

type Directory

type Directory []*DirEntry

func (Directory) Len

func (d Directory) Len() int

func (Directory) Less

func (d Directory) Less(i, j int) bool

func (Directory) Swap

func (d Directory) Swap(i, j int)

type Ino

type Ino uint64

func (*Ino) New

func (n *Ino) New(mode os.FileMode) *Inode

func (*Ino) NewDir

func (n *Ino) NewDir(mode os.FileMode) *Inode

func (*Ino) SubIno

func (n *Ino) SubIno()

type Inode

type Inode struct {
	sync.RWMutex

	Ino   uint64      // should never change
	Mode  fs.FileMode // should never change
	Nlink uint64
	Size  int64

	Ctime time.Time // creation time
	Atime time.Time // access time
	Mtime time.Time // modification time

	Dir Directory
}

An Inode represents the basic metadata of a file.

func (*Inode) IsDir

func (n *Inode) IsDir() bool

func (*Inode) Link

func (n *Inode) Link(name string, child *Inode) error

Link - link adds a directory entry (DirEntry) for the given node (assumed to be a directory) to the provided child Inode.

func (*Inode) Rename

func (n *Inode) Rename(oldpath, newpath string) error

func (*Inode) Resolve

func (n *Inode) Resolve(path string) (*Inode, error)

func (*Inode) Unlink

func (n *Inode) Unlink(name string) error

Unlink - removes the directory entry (DirEntry).

func (*Inode) UnlinkAll

func (n *Inode) UnlinkAll()
