pub enum DiffOp {
    Insert {
        id: WidgetId,
        parent: WidgetId,
        index: usize,
    },
    Remove {
        id: WidgetId,
    },
    Update {

    },
    Move {

    },
}

A single reconciliation operation produced by diff.

Variants

Insert

A new node id was added as a child of parent at child-list index index.

Fields

id: WidgetId

The node being inserted.

parent: WidgetId

The parent it is inserted under.

index: usize

The position within parent’s child list.

Remove

Node id (and its subtree) was removed.

Fields

id: WidgetId

The node being removed.

Update

Node id persists but one or more of its paint-relevant fields changed.

Fields

id: WidgetId

The node whose fields changed.

Move

Node id kept its parent but moved to a new index within the child list.

Fields

id: WidgetId

The node being moved.

parent: WidgetId

Its parent (unchanged).

index: usize

The new position within parent’s child list.

Trait Implementations

impl Clone for DiffOp

fn clone(&self) -> DiffOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffOp

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

Formats the value using the given formatter.

impl PartialEq for DiffOp

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