pub fn select<B>(self, other: B) -> Select<Self, <B as IntoFuture>::Future> where
    B: IntoFuture<Item = Self::Item, Error = Self::Error>, 

Waits for either one of two futures to complete.

pub fn select2<B>(self, other: B) -> Select2<Self, <B as IntoFuture>::Future> where
    B: IntoFuture, 

Waits for either one of two differently-typed futures to complete.

pub fn join<B>(self, other: B) -> Join<Self, <B as IntoFuture>::Future> where
    B: IntoFuture<Error = Self::Error>, 

Joins the result of two futures, waiting for them both to complete.
