pub fn create_with_properties( shape: ShapeKind, look: StyleAttr, orientation: Orientation, size: Point, properties: impl Into<String>, ) -> Element

pub fn move_to(&mut self, to: Point)

Trait Implementations

impl Clone for Element

fn clone(&self) -> Element

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Element

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

Formats the value using the given formatter.

impl Renderable for Element

fn render(&self, debug: bool, canvas: &mut dyn RenderBackend)

Render the shape into a canvas. If \p debug is set then extra markers will be rendered.

fn get_connector_location( &self, from: Point, force: f64, port: &Option<String>, ) -> (Point, Point)

\Return the coordinate for the connection point of an arrow that’s coming from the direction of \p from. The format of the path is (x, y, cx, cy), where cx and cy, are the control points of the bezier curve. \p force is the magnitude of the edge direction. \p port is the optional port name (for named records).

fn get_passthrough_path( &self, _from: Point, _to: Point, _force: f64, ) -> (Point, Point)

Computes the coordinate for the connection point of an arrow that’s passing through this edge. coming from the direction of \p from. \returns the bezier path in the format (x, y, cx, cy), where cx and cy, are the control points for the entry path of the bezier curve. The exit path is assumed to be the mirror point for the center (first point). \p force is the magnitude of the edge direction. This works with the get_connector_location method for drawing edges.

impl Visible for Element

fn position(&self) -> Position

\return the Position of the shape.

fn position_mut(&mut self) -> &mut Position

\return the mutable reference to the Position of the shape.

fn is_connector(&self) -> bool

Return true if the element is a connector.

fn transpose(&mut self)

Swap the coordinates of the location and size.

fn resize(&mut self)

Update the size of the shape.
