Trait Implementations

impl Clone for SingleVariantUnion

fn clone(&self) -> SingleVariantUnion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Constrained for SingleVariantUnion

type Constraint = ()

impl IntoNatural for SingleVariantUnion

type Natural = Option<SingleVariantUnion>

A good default type for this wire type to convert into.

fn into_natural(self) -> Self::Natural

Converts this type into its natural equivalent.

impl Wire for SingleVariantUnion

type Narrowed<'de> = SingleVariantUnion
