rustHow to join all futures in vector in Rust

Description: Joining all futures in a vector in Rust can be done using the join_all method from the futures crate. This method takes a vector of futures and returns a single future that resolves when all of the futures in the vector have resolved.

Code example:

use futures::{future, Future};

fn join_all_futures(futures: Vec<impl Future>) -> impl Future {
    future::join_all(futures)
}

Output The output of this code is a single future that resolves when all of the futures in the vector have resolved.

Explanation of Code Parts:

• use futures::{future, Future};: This imports the future and Future modules from the futures crate.
• fn join_all_futures(futures: Vec<impl Future>) -> impl Future {: This defines a function called join_all_futures that takes a vector of futures as an argument and returns a single future.
• future::join_all(futures): This calls the join_all method from the futures crate, which takes a vector of futures and returns a single future that resolves when all of the futures in the vector have resolved.
