    Interface MappingKeyStartedEvent

    Fired when a mapping-key sequence starts: the head key matched a registered mapping key and its target chain is about to run.

    interface MappingKeyStartedEvent {
        key: string;
        type: "started";
    }
    Index
    key: string

    The head key that started the sequence.

    type: "started"

    Event discriminant — always "started".
