[][src]Struct futures_util::future::Join4

#[must_use = "futures do nothing unless polled"]
pub struct Join4<Fut1: Future, Fut2: Future, Fut3: Future, Fut4: Future> { /* fields omitted */ }
[]

Future for the join4 combinator, waiting for four futures to complete.

This is created by the Future::join4 method.
