Trait Implementations

impl Clone for EmptyStructUnion

fn clone(&self) -> EmptyStructUnion

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Constrained for EmptyStructUnion

type Constraint = ()

Type of constraint information for this type.

fn validate( _: Slot<'_, EmptyStructUnion>, _: <EmptyStructUnion as Constrained>::Constraint, ) -> Result<(), ValidationError>

impl<___D> Decode<___D> for EmptyStructUnion

where ___D: InternalHandleDecoder + ?Sized,

fn decode( slot: Slot<'_, EmptyStructUnion>, decoder: &mut ___D, _: (), ) -> Result<(), DecodeError>

Decodes a value into a slot using a decoder.

impl<'a, ___E> EncodeOption<EmptyStructUnion, ___E> for &'a EmptyStructUnion

where &'a EmptyStructUnion: Encode<EmptyStructUnion, ___E>, ___E: ?Sized,

fn encode_option( this: Option<&'a EmptyStructUnion>, encoder: &mut ___E, out: &mut MaybeUninit<EmptyStructUnion>, _: (), ) -> Result<(), EncodeError>

impl IntoNatural for EmptyStructUnion

type Natural = Option<EmptyStructUnion>

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 EmptyStructUnion

type Narrowed<'de> = EmptyStructUnion
