Struct Node

struct Node<O> {
    obligation: O,
    state: Cell<NodeState>,
    dependents: Vec<usize>,
    has_parent: bool,
    obligation_tree_id: ObligationTreeId,
}

Fields§

§obligation: O§state: Cell<NodeState>§dependents: Vec<usize>

Obligations that depend on this obligation for their completion. They must all be in a non-pending state.

§has_parent: bool

If true, dependents[0] points to a “parent” node, which requires special treatment upon error but is otherwise treated the same. (It would be more idiomatic to store the parent node in a separate Option<usize> field, but that slows down the common case of iterating over the parent and other descendants together.)

§obligation_tree_id: ObligationTreeId

Identifier of the obligation tree to which this node belongs.
