Enum Void 

pub enum Void {}

The empty sum (uninhabited type for terminating sum chains).

Analogous to ! (never type). No values of this type can exist.

Trait Implementations

impl Clone for Void

fn clone(&self) -> Void

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Void

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Diff for Void

type Diff = VoidDiff

The diff representation for this type.

fn diff(old: &Self, _new: &Self) -> VoidDiff

Compute the diff from old to new.

impl Hash for Void

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Void

fn eq(&self, other: &Void) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Patch for Void

fn patch(old: &Self, _diff: &VoidDiff) -> Self

Apply the diff to old to produce new.

impl SumLen for Void

fn sum_len() -> usize

impl Copy for Void

impl Eq for Void

impl StructuralPartialEq for Void
