Implementations

impl VisualGraph

pub fn new(orientation: Orientation) -> Self

pub fn orientation(&self) -> Orientation

pub fn num_nodes(&self) -> usize

pub fn iter_nodes(&self) -> NodeIterator

pub fn succ(&self, node: NodeHandle) -> &Vec<NodeHandle>

pub fn preds(&self, node: NodeHandle) -> &Vec<NodeHandle>

pub fn pos(&self, n: NodeHandle) -> Position

pub fn pos_mut(&mut self, n: NodeHandle) -> &mut Position

pub fn is_connector(&self, n: NodeHandle) -> bool

pub fn transpose(&mut self)

pub fn element(&self, node: NodeHandle) -> &Element

pub fn element_mut(&mut self, node: NodeHandle) -> &mut Element

pub fn add_node(&mut self, elem: Element) -> NodeHandle

Add a node to the graph. \returns a handle to the node.

pub fn add_edge(&mut self, arrow: Arrow, from: NodeHandle, to: NodeHandle)

Add an edge to the graph.

impl VisualGraph

pub fn do_it(
    &mut self,
    debug_mode: bool,
    disable_opt: bool,
    disable_layout: bool,
    rb: &mut dyn RenderBackend
)

pub fn to_valid_dag(&mut self)

Flip the edges in the graph to create a valid dag. This is the first step of graph canonicalization.

pub fn split_text_edges(&mut self)

Convert all of the edges that contain text labels to edges that go through connectors. This is the second step of graph canonicalization.

pub fn split_long_edges(&mut self, disable_optimizations: bool)

pub fn expand_self_edges(&mut self)

Convert all of the saved self edges into proper edges in the graph.
