Struct Node 

pub struct Node<T = ()> {

    pub id: Id,
    pub position: Point,
    pub label: String,
    pub data: T,
    pub node_type: Option<String>,
    pub source_side: Side,
    pub target_side: Side,
    pub draggable: bool,
    pub selectable: bool,
    pub selected: bool,
    pub size: Option<Size>,
    pub measured: Option<Size>,
    pub class: Option<String>,
    pub style: Option<String>,
}

A node in the flow graph.

T is a user-defined payload available to custom node renderers.

Fields

id: Id

position: Point

Position of the node’s top-left corner, in flow coordinates.

label: String

Label rendered by the default node view.

data: T

Custom payload for custom node views.

node_type: Option<String>

Node type tag. The default view recognizes "input" (source handle only) and "output" (target handle only); custom views can match on any value.

source_side: Side

Side where outgoing edges leave (used by the default view’s source handle and as the anchor fallback).

target_side: Side

Side where incoming edges arrive.

draggable: bool

selectable: bool

selected: bool

size: Option<Size>

Explicit size. When None (default) the node sizes to its content and is measured automatically.

measured: Option<Size>

Measured size, maintained by the framework.

class: Option<String>

Extra CSS classes for the node wrapper (e.g. Tailwind utilities).

style: Option<String>

Extra inline CSS for the node wrapper.

Implementations

impl Node<()>

pub fn new( id: impl Into<Id>, label: impl Into<String>, position: impl Into<Point>, ) -> Self

Create a node with the default (unit) payload.

impl<T> Node<T>

pub fn with_data( id: impl Into<Id>, label: impl Into<String>, position: impl Into<Point>, data: T, ) -> Self

Create a node carrying a custom payload.

pub fn node_type(self, ty: impl Into<String>) -> Self

pub fn size(self, size: impl Into<Size>) -> Self

pub fn class(self, class: impl Into<String>) -> Self

pub fn style(self, style: impl Into<String>) -> Self

pub fn draggable(self, draggable: bool) -> Self

pub fn selectable(self, selectable: bool) -> Self

pub fn sides(self, target: Side, source: Side) -> Self

Set both handle sides at once, e.g. for horizontal layouts sides(Side::Left, Side::Right) (incoming left, outgoing right).

pub fn rect(&self) -> Rect

The node’s current rectangle (explicit size, else measured, else a default estimate).
