Redux工具包typescript --我的PayloadAction类型是什么？

type PayloadAction<Payload, Type extends string = string, Meta = never, Error = never> = {
  type: Type;
  payload: Payload;
  meta?: Meta;
  error?: Error;
};

const increment = createAction<number>('INCREMENT');
const decrement = createAction<number>('DECREMENT');

const initialState = { count: 0 };

const counterReducer = createReducer(initialState, (builder) => {
  builder
    .addCase(increment, (state, action) => {
      state.count += action.payload;
    })
    .addCase(decrement, (state, action) => {
      state.count -= action.payload;
    });
});
