Enum VoidDiff 

pub enum VoidDiff {}

Void has no values, so Diff is trivially never called. We need the impl for sum chains to terminate.

Trait Implementations

impl Clone for VoidDiff

fn clone(&self) -> VoidDiff

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VoidDiff

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

Formats the value using the given formatter.

impl DiffInfo for VoidDiff

fn is_empty(&self) -> bool

Whether the diff represents no changes (identity patch).

fn change_count(&self) -> usize

Number of changed fields/variants.

impl PartialEq for VoidDiff

fn eq(&self, other: &VoidDiff) -> 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.
