Struct rustc_data_structures::graph::dominators::Dominators

impl<Node: Idx> Dominators<Node>

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

Returns true if node is reachable from the start node.

pub fn immediate_dominator(&self, node: Node) -> Option<Node>

Returns the immediate dominator of node, if any.

pub fn cmp_in_dominator_order(&self, lhs: Node, rhs: Node) -> Ordering

Provide deterministic ordering of nodes such that, if any two nodes have a dominator relationship, the dominator will always precede the dominated. (The relative ordering of two unrelated nodes will also be consistent, but otherwise the order has no meaning.) This method cannot be used to determine if either Node dominates the other.

pub fn dominates(&self, a: Node, b: Node) -> bool

Returns true if a dominates b.

§Panics

Panics if b is unreachable.
