Derived Implementations

impl Debug for Generics

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

Formats the value using the given formatter.

impl Hash for Generics

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

Feeds a slice of this type into the state provided.

impl Decodable for Generics

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

impl Encodable for Generics

fn encode<__S: Encoder>(&self, __arg_0: &mut __S) -> Result<(), __S::Error>

impl Eq for Generics

impl PartialEq for Generics

fn eq(&self, __arg_0: &Generics) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Generics) -> bool

This method tests for !=.

impl Clone for Generics

fn clone(&self) -> Generics

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
