我试图在枚举上使用映射类型：

export enum CurrencyType {
  USD = "USD",
  AUD = "AUD",
  GBP = "GBP",
  CAD = "CAD"
}

实现这种类型：

type Rates = {
  AUD: number;
  CAD: number;
  GBP: number;
  USD: number;
}

我以为我可以做这样的事情：

type Rates = {
  [P in keyof CurrencyType]: number;
};

但是结果是这样的：

type Rates = {
    toString: number;
    charAt: number;
    charCodeAt: number;
    concat: number;
    indexOf: number;
    lastIndexOf: number;
    localeCompare: number;
    match: number;
    replace: number;
    //...
}

我尝试使用union literals替代enum，

export type CurrencyType = …
