type DirEntry ¶

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

DirEntry is a directory entry.

type DirEntry interface {
	// Name returns the name of the file (or subdirectory) described by the entry.
	// This name is only the final element of the path (the base name), not the entire path.
	// For example, Name would return "hello.go" not "home/gopher/hello.go".
	Name() string
	// IsDir reports whether the entry describes a directory.
	IsDir() bool
	// Type returns the type bits for the entry.
	// The type bits are a subset of the usual FileMode bits, those returned by the FileMode.Type method.
	Type() FileMode
	// Info returns the FileInfo for the file or subdirectory described by the entry.
	// The returned FileInfo may be from the time of the original directory read
	// or from the time of the call to Info. If the file has been removed or renamed
	// since the directory read, Info may return an error satisfying errors.Is(err, ErrNotExist).
	// If the entry denotes a symbolic link, Info reports the information about the link itself,
	// not the link's target.
	Info() (FileInfo, error)
}

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

FS is a simple virtual file system.

type File ¶

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

File is a virtual file.

    Stat() (FileInfo, error)
    Read([]byte) (int, error)
    Close() error
}

func NewFile(name string, contents []byte) *File

type FileInfo ¶

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

FileInfo is information on a file.

type FileInfo interface {
    Name() string       // base name of the file
    Size() int64        // length in bytes for regular files; system-dependent for others
    Mode() FileMode     // file mode bits
    ModTime() time.Time // modification time
    IsDir() bool        // abbreviation for Mode().IsDir()
    Sys() interface{}   // underlying data source (can return nil)
}

func (f *FileInfo) IsDir() bool

func (f *FileInfo) ModTime() time.Time

func (f *FileInfo) Mode() fs.FileMode

func (f *FileInfo) Name() string

func (f *FileInfo) Size() int64
