fn poll(&mut self) -> Poll<Self::Item, Self::Error>

fn from_err<E>(self) -> FromErr<Self, E>where
    E: From<Self::Error>,
    Self: Sized,

    F: FnOnce(Self::Error) -> B,
    B: IntoFuture<Item = Self::Item>,
    Self: Sized,

Execute another future if this one resolves with an error.

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

Waits for either one of two futures to complete.

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

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

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

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