Struct nannou::draw::Drawing

pub struct Drawing<'a, T> { /* private fields */ }

A Drawing in progress.

Drawing provides a way of chaining together method calls describing properties of the thing that we are drawing. Drawing ends when the instance is Dropped, at which point the properties of the drawing are inserted into the Draw type.

When a Drawing begins, a node is immediately created for the drawing within the Draw’s inner geom::Graph. This ensures the correct instantiation order is maintained within the graph. As a result, each Drawing is associated with a single, unique node. Thus a Drawing can be thought of as a way of specifying properties for a node.

Implementations
