Type Alias PairResolution

One pair's outcome. Exactly one of nodeId/candidateId is set — candidateId is the id the node would have, so callers can keep addressing an unresolved pair by what it asked for. A pair with no candidate at all (an unknown key) is null.

type PairResolution = {
    candidateId?: string;
    nodeId?: string;
    pairIndex: number;
}
