    N: Copy + Eq + Hash,
{ /* private fields */ }
Expand description

The dominance relation for some graph and root.

Implementations§

Source§

impl<N> Dominators<N>
where N: Copy + Eq + Hash,

Source

pub fn root(&self) -> N

Get the root node used to construct these dominance relations.

Source

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

Get the immediate dominator of the given node.

Returns None for any node that is not reachable from the root, and for the root itself.

Source

pub fn strict_dominators(&self, node: N) -> Option<DominatorsIter<'_, N>>

Iterate over the given node’s strict dominators.

If the given node is not reachable from the root, then None is returned.

Source

pub fn dominators(&self, node: N) -> Option<DominatorsIter<'_, N>>

Iterate over all of the given node’s dominators (including the given node itself).

If the given node is not reachable from the root, then None is returned.

Source

pub fn immediately_dominated_by(&self, node: N) -> DominatedByIter<'_, N> ⓘ

Iterate over all nodes immediately dominated by the given node (not including the given node itself).
