Types

type DiskFS 

type DiskFS struct {
}

DiskFS implement file system on disk

func (*DiskFS) MkdirAll 

func (dfs *DiskFS) MkdirAll(path string, perm os.FileMode) error

MkdirAll creates a directory named path

func (*DiskFS) Open 

func (dfs *DiskFS) Open(name string) (File, error)

Open opens the named file for reading. If successful, methods on the returned file can be used for reading; the associated file descriptor has mode O_RDONLY. If there is an error, it will be of type *PathError.

func (*DiskFS) OpenFile 

func (dfs *DiskFS) OpenFile(name string, flag int, perm os.FileMode) (File, error)

func (*DiskFS) ReadFile 

func (dfs *DiskFS) ReadFile(name string) ([]byte, error)

ReadFile reads the file named by filename and returns the contents.

func (*DiskFS) Remove 

func (dfs *DiskFS) Remove(name string) error

Remove removes the named file or (empty) directory. If there is an error, it will be of type *PathError.

func (*DiskFS) Stat added in v1.8.8 

func (dfs *DiskFS) Stat(name string) (fs.FileInfo, error)

Stat returns a FileInfo describing the named file. If there is an error, it will be of type *PathError.

func (dfs *DiskFS) WriteFile(name string, data []byte, perm os.FileMode) error

WriteFile writes data to a file named by filename.

type FS 

type FS interface {
