Trait Diff 

pub trait Diff: Sized {
    type Diff: DiffInfo;

    // Required method
    fn diff(old: &Self, new: &Self) -> Self::Diff;
}

Compute a structural diff between two values of the same type.

The diff type Self::Diff captures what changed between old and new.

Required Associated Types

type Diff: DiffInfo

The diff representation for this type.

Required Methods

fn diff(old: &Self, new: &Self) -> Self::Diff

Compute the diff from old to new.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementors

impl Diff for Void

type Diff = VoidDiff

impl Diff for Unit

type Diff = UnitDiff

impl<H: Diff, T: Diff> Diff for Product<H, T>

type Diff = ProductDiff<<H as Diff>::Diff, <T as Diff>::Diff>

impl<L: Diff + Clone, R: Diff + Clone> Diff for Sum<L, R>

type Diff = SumDiff<<L as Diff>::Diff, <R as Diff>::Diff, L, R>

where T: LeafDiff + Clone + PartialEq,

Blanket leaf-level diff: compare via PartialEq, delta is the new value.

type Diff = Delta<T>

impl<T: Diff> Diff for Field<T>

type Diff = <T as Diff>::Diff

impl<T: Diff> Diff for Variant<T>

type Diff = <T as Diff>::Diff
