Types

type AuthorizeFunc added in v1.10.0 

type AuthorizeFunc func(msg string) (string, error)

type DiskFS 

type DiskFS struct {
}

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.
