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

type Node = ConstraintSccIndex
type Edge = (ConstraintSccIndex, ConstraintSccIndex)
source§fn graph_id(&'this self) -> Id<'this>
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>
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>>
fn node_shape( &'this self, _node: &ConstraintSccIndex, ) -> Option<LabelText<'this>>
source§fn 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
.source§fn 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.source§fn 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.source§fn 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.Auto Trait Implementations§

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.
