Trait Implementations

impl<T> Hash for Discriminant<T>

fn hash<H>(&self, state: &mut H) where H: Hasher

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<T> PartialEq<Discriminant<T>> for Discriminant<T>

fn eq(&self, rhs: &Discriminant<T>) -> bool

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

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl<T> Clone for Discriminant<T>

fn clone(&self) -> Discriminant<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Eq for Discriminant<T>

impl<T> Copy for Discriminant<T>

impl<T> Debug for Discriminant<T>

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