type Node = ConstraintSccIndex
type Edge = (ConstraintSccIndex, ConstraintSccIndex)
sourcefn nodes(&'this self) -> Nodes<'this, ConstraintSccIndex>
fn nodes(&'this self) -> Nodes<'this, ConstraintSccIndex>
Returns all the nodes in this graph.
sourcefn edges(&'this self) -> Edges<'this, (ConstraintSccIndex, ConstraintSccIndex)>
fn edges(&'this self) -> Edges<'this, (ConstraintSccIndex, ConstraintSccIndex)>
Returns all of the edges in this graph.
sourcefn source(
&'this self,
edge: &(ConstraintSccIndex, ConstraintSccIndex)
) -> ConstraintSccIndex
fn source(
&'this self,
edge: &(ConstraintSccIndex, ConstraintSccIndex)
) -> ConstraintSccIndex
The source node for edge.
sourcefn target(
&'this self,
edge: &(ConstraintSccIndex, ConstraintSccIndex)
) -> ConstraintSccIndex
fn target(
&'this self,
edge: &(ConstraintSccIndex, ConstraintSccIndex)

type Node = ConstraintSccIndex
type Edge = (ConstraintSccIndex, ConstraintSccIndex)
sourcefn graph_id(&'this self) -> Id<'this>
fn graph_id(&'this self) -> Id<'this>
Must return a DOT compatible identifier naming the graph.
sourcefn node_id(&'this self, n: &ConstraintSccIndex) -> Id<'this>
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. Read more
sourcefn node_shape(
&'this self,
_node: &ConstraintSccIndex
) -> Option<LabelText<'this>>
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. Read more
sourcefn node_label(&'this self, n: &ConstraintSccIndex) -> LabelText<'this>
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. Read more
sourcefn edge_label(&'a self, _e: &Self::Edge) -> LabelText<'a>
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. Read more
sourcefn node_style(&'a self, _n: &Self::Node) -> Style
fn node_style(&'a self, _n: &Self::Node) -> Style
Maps n to a style that will be used in the rendered output.
sourcefn edge_style(&'a self, _e: &Self::Edge) -> Style
fn edge_style(&'a self, _e: &Self::Edge) -> Style
Maps e to a style that will be used in the rendered output.

Layout
Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
