Enum SumDiff 

pub enum SumDiff<LD, RD, L, R> {
    BothLeft(LD),
    BothRight(RD),
    LeftToRight(R),
    RightToLeft(L),
}

Diff of a sum type: either both are the same variant (structural diff) or the variant changed (full replacement).

Variants

BothLeft(LD)

Both values are Left; contains diff of inner values.

BothRight(RD)

Both values are Right; contains diff of inner values.

LeftToRight(R)

Variant changed from Left to Right.

RightToLeft(L)

Variant changed from Right to Left.

Trait Implementations

impl<LD: Clone, RD: Clone, L: Clone, R: Clone> Clone for SumDiff<LD, RD, L, R>

fn clone(&self) -> SumDiff<LD, RD, L, R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<LD: Debug, RD: Debug, L: Debug, R: Debug> Debug for SumDiff<LD, RD, L, R>

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

Formats the value using the given formatter.

impl<LD: DiffInfo, RD: DiffInfo, L, R> DiffInfo for SumDiff<LD, RD, L, R>

fn is_empty(&self) -> bool

Whether the diff represents no changes (identity patch).

fn change_count(&self) -> usize

Number of changed fields/variants.

impl<LD: PartialEq, RD: PartialEq, L: PartialEq, R: PartialEq> PartialEq for SumDiff<LD, RD, L, R>

fn eq(&self, other: &SumDiff<LD, RD, L, R>) -> 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.
