	// BindataFn is a function to access binary data outside of os.Open

Functions

func Open

func Open(file string) (io.ReadCloser, error)

Open is a wrapper around os.Open that will also check BindataFn to access embedded data. The intended use is to use the an embedding library to create an Asset function that matches this signature.

func ReadDir

func ReadDir(file string) ([]os.FileInfo, error)

ReadDir replaces ioutil.ReadDir, trying to use the BinaryDir if it exists.

func ReadFile

func ReadFile(file string) ([]byte, error)

ReadFile replaces ioutil.ReadFile, trying to use the BindataFn if it exists.
