import { to } from 'await-to-arkts';
import { promptAction } from '@kit.ArkUI';

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  async onClickHandler(_: ClickEvent) {
    const getLongLived = (): Promise<IPerson> => {
      return new Promise((resolve, reject) => {
        const age = Math.ceil(Math.random() * 200);
        const person = { name: 'zhang3', age, remark: '法外狂徒' } as IPerson;

        if (age < 100) {
          return reject(new Error('He is not a long-lived person!'));
        }

        resolve(person);
      })
    }

    const result = await to(getLongLived());
    const err = result[0];
    const person = result[1];

    if (err) {
      // 处理异常
      promptAction.showToast({
        message: err.message,
      });

      return;
    }

    // success case, do something
    console.log(`老人家高寿：${person?.age}`)
  }

  build() {
