fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl LoadableMetadata for Metadata

fn load<R: ?Sized + BufRead>(r: &mut R) -> Result<Metadata>

Loads the implementing type from the given buffered input stream.

fn load_from_seek<R: ?Sized + BufRead + Seek>(r: &mut R) -> Result<Self>

Loads the implementing type from the given buffered and seekable input stream.

fn load_from_file<P: AsRef<Path>>(path: P) -> Result<Self>
