Enum rustc_data_structures::graph::iterate::NodeStatus

pub enum NodeStatus {
    Visited,
    Settled,
}

The status of a node in the depth-first search.

See the documentation of TriColorDepthFirstSearch to see how a node’s status is updated during DFS.

Variants

Visited

This node has been examined by the depth-first search but is not yet Settled.

Also referred to as “gray” or “discovered” nodes in CLR.

Settled

This node and all nodes reachable from it have been examined by the depth-first search.

Also referred to as “black” or “finished” nodes in CLR.
