How to wait for a list of async function calls in rust?

Question

I have a list of async functions in rust that I want to execute concurrently and then wait for all them to finish. The working code I have right now is

Answer 1

So after some searching I found that rust futures has a function called join_all which allows for waiting on a collection of futures.

 use futures::future::join_all;
 ....

 async fn start_consumers(&self) {
    let mut v = Vec::new();
    for consumer in &self.consumers {
        v.push(consumer.consume());
    }
    join_all(v).await;
 }
