Function embassy_futures::join::join

pub fn join<Fut1, Fut2>(future1: Fut1, future2: Fut2) -> Join<Fut1, Fut2> where
    Fut1: Future,
    Fut2: Future,

合并两个future的结果，等待他们都完成

本函数将以await的方式等待两个future都完成，并返回一个新的future 返回的future会以两个future的结果所组成的元组的方式进行输出。

注意，该函数会消耗传递的future，并会返回一个对其进行了封装的版本。

---

Joins the result of two futures, waiting for them both to complete.

This function will return a new future which awaits both futures to complete. The returned future will finish with a tuple of both results.

Note that this function consumes the passed futures and returns a wrapped version of it.

Examples

let a = async { 1 };
let b = async { 2 };
let pair = embassy_futures::join::join(a, b).await;

assert_eq!(pair, (1, 2));
