polkadot.js:无法创建Enum

Question

types.json

{
  "WorkerId": {
    "_enum": {
      "Single": "Single",
      "Double": "Double"
    }
  },
  "Single": "u8",
  "Double": "(u8, u8)",
}

基板代码：

#[pallet::storage]
#[pallet::getter(fn worker_infos)]
pub type WorkerInfos<T: Config> = StorageMap<_, Twox64Concat, WorkerId, WorkerInfo, ValueQuery>;


pub enum WorkerId {
    Single(u8),
    Double(u8, u8),
}

我想在worker_infos中通过WorkerId查询polkadot.js：

    workerIds = [1,2]
    api.query[wrpc][wcallable]
      .multi(workerIds, (results) => {
        ...
      })
      .then((unsub) => {
        ...
      })
      .catch(console.error);

错误信息：

REGISTRY: Error: Unable to create Enum via index 2, in Single, Double

对此有什么想法吗？如何在polkadot.js?中传递workerIds(枚举类型)

Answer 1

{单:1}或{双: 2，3}
