Trait Implementations§

source§

impl<'a> GraphWalk<'a> for GraphvizDepGraph

§

type Node = DepKind

§

type Edge = (DepKind, DepKind)

source§

fn nodes(&self) -> Nodes<'_, DepKind>

Returns all the nodes in this graph.
source§

fn edges(&self) -> Edges<'_, (DepKind, DepKind)>

Returns all of the edges in this graph.
source§

fn source(&self, edge: &(DepKind, DepKind)) -> DepKind

The source node for edge.
source§

fn target(&self, edge: &(DepKind, DepKind)) -> DepKind

The target node for edge.
source§

impl<'a> Labeller<'a> for GraphvizDepGraph

§

type Node = DepKind

§

type Edge = (DepKind, DepKind)

source§

fn graph_id(&self) -> Id<'_>

Must return a DOT compatible identifier naming the graph.
source§

fn node_id(&self, n: &DepKind) -> Id<'_>

Maps n to a unique identifier with respect to self. The implementor is responsible for ensuring that the returned name is a valid DOT identifier.
source§

fn node_label(&self, n: &DepKind) -> LabelText<'_>

Maps n to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is just the output from node_id.
source§

fn node_shape(&'a self, _node: &Self::Node) -> Option<LabelText<'a>>

Maps n to one of the graphviz shape names. If None is returned, no shape attribute is specified.
source§

fn edge_label(&'a self, _e: &Self::Edge) -> LabelText<'a>

Maps e to a label that will be used in the rendered output. The label need not be unique, and may be the empty string; the default is in fact the empty string.
source§

fn node_style(&'a self, _n: &Self::Node) -> Style

Maps n to a style that will be used in the rendered output.
source§

fn edge_style(&'a self, _e: &Self::Edge) -> Style

Maps e to a style that will be used in the rendered output.
