class MuxAsyncIterator implements AsyncIterable<T>import { MuxAsyncIterator } from "https://deno.land/std@0.146.0/async/mod.ts"; The MuxAsyncIterator class multiplexes multiple async iterators into a single stream. It currently makes an assumption: The final result (the value returned and not yielded from the iterator) does not matter; if there is any, it is discarded.
