Trait Implementations§

source§

impl<'a, 'this, 'tcx> GraphWalk<'this> for SccConstraints<'a, 'tcx>

source§

type Node = ConstraintSccIndex

source§

type Edge = (ConstraintSccIndex, ConstraintSccIndex)

source§

fn nodes(&'this self) -> Nodes<'this, ConstraintSccIndex>

Returns all the nodes in this graph.
source§

fn edges(&'this self) -> Edges<'this, (ConstraintSccIndex, ConstraintSccIndex)>

Returns all of the edges in this graph.
source§

fn source( &'this self, edge: &(ConstraintSccIndex, ConstraintSccIndex), ) -> ConstraintSccIndex

The source node for edge.
source§

fn target( &'this self, edge: &(ConstraintSccIndex, ConstraintSccIndex), ) -> ConstraintSccIndex

The target node for edge.
source§

impl<'a, 'this, 'tcx> Labeller<'this> for SccConstraints<'a, 'tcx>

source§

type Node = ConstraintSccIndex

source§

type Edge = (ConstraintSccIndex, ConstraintSccIndex)

source§

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

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

fn node_id(&'this self, n: &ConstraintSccIndex) -> Id<'this>

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_shape( &'this self, _node: &ConstraintSccIndex, ) -> Option<LabelText<'this>>

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

fn node_label(&'this self, n: &ConstraintSccIndex) -> LabelText<'this>

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 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.
