Struct SpantreeBuilder

Source
struct SpantreeBuilder<'a, Node: Idx> {
    supernodes: &'a IndexSlice<Node, Node>,
    succ_supernodes: &'a IndexSlice<Node, Node>,
    is_unvisited: DenseBitSet<Node>,

    counter_terms: IndexVec<Node, Vec<CounterTerm<Node>>>,

Fields§

§supernodes: &'a IndexSlice<Node, Node>§succ_supernodes: &'a IndexSlice<Node, Node>§is_unvisited: DenseBitSet<Node>§span_edges: IndexVec<Node, Option<SpantreeEdge<Node>>>

Links supernodes to each other, gradually forming a spanning tree of the merged-flow graph.

A supernode without a span edge is the root of its component of the spantree. Nodes that aren’t supernodes cannot have a spantree edge.

§yank_buffer: Vec<Node>

Shared path buffer recycled by all calls to yank_to_spantree_root.

§counter_terms: IndexVec<Node, Vec<CounterTerm<Node>>>

An in-progress counter expression for each node. Each expression is initially empty, and will be filled in as relevant nodes are visited.

Implementations§

Source§

impl<'a, Node: Idx> SpantreeBuilder<'a, Node>

Source

fn new(node_flow_data: &'a NodeFlowData<Node>) -> Self

Source

fn is_supernode(&self, node: Node) -> bool

Source

fn spantree_root(&self, this: Node) -> Node

Given a supernode, finds the supernode that is the “root” of its spantree component. Two nodes that have the same spantree root are connected in the spantree.

Source

fn yank_to_spantree_root(&mut self, this: Node)

Rotates edges in the spantree so that this is the root of its spantree component.

Source

fn visit_node(&mut self, this: Node)

Must be called exactly once for each node in the balanced-flow graph.

Source

fn finish(self) -> IndexVec<Node, Vec<CounterTerm<Node>>>

Asserts that all nodes have been visited, and returns the computed counter expressions (made up of physical counters) for each node.
