Struct JoinAll 

pub struct JoinAll<'a, T> { /* private fields */ }

Join N futures, where N is known only at run time (D82).

join2 covers the fixed-arity case the join! macro expands to; this covers a Vec built at run time — a parent joining however many children it has, or a virtual sequence joining a list of sub-sequences. Every future is polled on each wake until all have completed; results come back in the original order. Like Join2, the futures may borrow ('a).

Trait Implementations

impl<T> Future for JoinAll<'_, T>

type Output = Vec<T>

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Vec<T>>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
