Struct NodeGraphViewState 

pub struct NodeGraphViewState {
    pub pan: CanvasPoint,
    pub zoom: f32,
    pub selected_nodes: Vec<NodeId>,
    pub selected_edges: Vec<EdgeId>,
    pub selected_groups: Vec<GroupId>,
    pub draw_order: Vec<NodeId>,
    pub edge_draw_order: Vec<EdgeId>,
    pub group_draw_order: Vec<GroupId>,
}

Node graph editor view-state.

This is intentionally separate from graph semantics and may be stored per-user/per-project.

Fields

pan: CanvasPoint

Canvas pan in graph space.

zoom: f32

Zoom factor.

selected_nodes: Vec<NodeId>

Selected nodes (optional).

selected_edges: Vec<EdgeId>

Selected edges (optional).

selected_groups: Vec<GroupId>

Selected groups (optional).

draw_order: Vec<NodeId>

Explicit draw order (optional).

edge_draw_order: Vec<EdgeId>

Explicit edge draw order (optional).

group_draw_order: Vec<GroupId>

Explicit group draw order (optional).

Implementations

impl NodeGraphViewState

pub fn set_viewport(&mut self, pan: CanvasPoint, zoom: f32)

pub fn set_selection( &mut self, nodes: Vec<NodeId>, edges: Vec<EdgeId>, groups: Vec<GroupId>, )

pub fn sanitize_for_graph(&mut self, graph: &Graph)

Removes stale IDs (selection / draw order) that no longer exist in the target graph.

pub fn sanitize_viewport(&mut self)

Trait Implementations

impl Clone for NodeGraphViewState

fn clone(&self) -> NodeGraphViewState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeGraphViewState

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

Formats the value using the given formatter.

impl Default for NodeGraphViewState

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for NodeGraphViewState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&NodeGraphViewState> for NodeGraphPureViewState

fn from(value: &NodeGraphViewState) -> Self

Converts to this type from the input type.

impl From<NodeGraphPureViewState> for NodeGraphViewState

fn from(value: NodeGraphPureViewState) -> Self

Converts to this type from the input type.

impl From<NodeGraphViewState> for NodeGraphPureViewState

fn from(value: NodeGraphViewState) -> Self

Converts to this type from the input type.

impl PartialEq for NodeGraphViewState

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

impl Serialize for NodeGraphViewState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
