substrate - 如何在 polkadot.js 中配置枚举

Question

以下是我的基板代码：

pub type ItemId = u8;
#[derive(Encode, Decode, Copy, Clone, PartialEq, Eq, RuntimeDebug)]
pub enum PoolId {
    TX(ItemId),
}

如何在json文件中配置枚举类型？https://polkadot.js.org/apps

这不起作用：

{
  "PoolId": {
    "_enum": [
      "TX"
    ]
  },
}

Answer 1

{
  "PoolId": {
    "_enum": [
      "TX"
    ]
  },
  "TX": "u8"
// or
// "TX": { "_": "u8" }
// or
// "TX": "ItemId",
// "ItemId": "u8"
// or
// "TX": { "_": "ItemId" },
// "ItemId": "u8"
}
