Types

type File

type File interface {
	io.Reader
	io.Seeker
	io.Closer
}

File provides the interface implemented by values returned from a file system's Open method.

type FileSystem

type FileSystem interface {
	Open(path string) (File, error)
	Lstat(path string) (os.FileInfo, error)
	Readlink(path string) (string, error)
	Readdirnames(path string) ([]string, error)
}

FileSystem provides the interface for operations over a file system.

func Map

func Map(m map[string][]byte, links []string) FileSystem

Map returns a FileSystem for m, wherein keys are file paths and values are file contents. File paths should not contain a leading slash. If links is not nil, it will be used to simulate symbolic links: for each key in m that is also in links, its value in m is treated as the link target.

func OS

func OS() FileSystem

OS returns a FileSystem for working with os files.
