是否可以在MST中创建文字数组类型?它应该等同于
type Interval = ['1min', '5min']
;
这是一个抛出错误的代码示例
type Interval = '1min' | '5min';
export interface AppStore {
config: {
intervals: ['1min', '5min']
},
search: {
symbol: string;
interval: string;
dataTypes: string[];
}
}
const appStore = types
.model<AppStore>('appStore', {
config: types.model({
intervals: types.array(
types.literal<Interval>('1min'),
types.literal<Interval>('5min')
),
}),
search: types.model({
dataTypes: types.array( types.string ),
interval: types.union(
types.literal<Interval>('1min'),
types.literal<Interval>('5min')
),
symbol: types.string,
}),
})
types.array()
期望有一个参数,所以它甚至可能吗? MST文档https://github.com/mobxjs/mobx-state-tree#types-overview
答案 0 :(得分:1)
你能详细说明一下,你在寻找数组类型还是元组类型?换句话说,是[&#34; 1min&#34;],还是[&#34; 1min&#34;,&#34; 5min&#34;,&#34; 1min&#34;]也可以接受?
如果这是可以接受的,则types.array(types.union(types.literal(&#34; 1min&#34;),types.literal(&#34; 5min&#34;))应该做的伎俩(你很接近!)。或者更简单:types.array(types.enum([&#34; 1min&#34;,&#34; 5min&#34;])))
如果您正在寻找尚未实现的元组类型:请参阅https://github.com/mobxjs/mobx-state-tree/issues/805
