impl Decodable for Arg

fn decode<__D: Decoder>(__arg_0: &mut __D) -> Result<Arg, __D::Error>

Deserialize a value using a Decoder.

impl Hash for Arg

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the state given, updating the hasher as necessary.

fn hash_slice<H>(data: &[Self], state: &mut H) where H: Hasher
