Struct NodeGraphChanges 

pub struct NodeGraphChanges {
    pub nodes: Vec<NodeChange>,
    pub edges: Vec<EdgeChange>,
}

XyFlow-style node/edge projection of a graph patch.

This adapter is intentionally lossy: it only contains node and edge changes. Use crate::runtime::commit::NodeGraphPatch when a consumer must observe full graph resources such as ports, groups, sticky notes, imports, or symbols.

Fields

nodes: Vec<NodeChange>

edges: Vec<EdgeChange>

Implementations

impl NodeGraphChanges

pub fn from_parts(nodes: Vec<NodeChange>, edges: Vec<EdgeChange>) -> Self

pub fn into_parts(self) -> (Vec<NodeChange>, Vec<EdgeChange>)

pub fn is_empty(&self) -> bool

pub fn nodes(&self) -> &[NodeChange]

pub fn edges(&self) -> &[EdgeChange]

pub fn from_patch(patch: &NodeGraphPatch) -> Self

pub fn from_transaction(tx: &GraphTransaction) -> Self

Derives change events from a reversible graph transaction.

This is intended for XyFlow-style callbacks such as “on_nodes_change”.

pub fn to_transaction( &self, graph: &Graph, ) -> Result<GraphTransaction, ChangesToTransactionError>

Converts change events into a reversible transaction by looking up “from” values in the current graph.

This enables an XyFlow-like runtime to accept (NodeChange, EdgeChange) and still keep GraphHistory undo/redo semantics.

Trait Implementations

impl Clone for NodeGraphChanges

fn clone(&self) -> NodeGraphChanges

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeGraphChanges

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

Formats the value using the given formatter.

impl Default for NodeGraphChanges

fn default() -> NodeGraphChanges

Returns the “default value” for a type.
