Struct JoinAll 

Source 
pub struct JoinAll<H: Future, T: Future> {
    pub head: H,
    pub tail: T,
    pub head_res: Option<H::Output>,
    pub tail_res: Option<T::Output>,

Expand description

A Future that polls two sub-futures and stores their outputs.

Once both futures resolve, the outputs are returned as a tuple.
