Struct nannou::ui::prelude::widget::graph::NodeContext

pub struct NodeContext<'a, NI> where
    NI: 'a + NodeId,  { /* fields omitted */ }

A context for a node yielded during the node instantiation stage.

This type can be used to:

1. Get the position of the node via point().
2. Get the ID for this node via node_id().
3. Convert into a NodeWidget ready for instantiation within the Ui via widget(a_widget).
