[+] Show hidden undocumented items

type Item = (Client, Connection<Socket, T::Stream>)

The type of value that this future will resolved with if it is successful.

type Error = Error

The type of error that this future will resolve with if it fails in a normal fashion.

fn poll(&mut self) -> Poll<(Client, Connection<Socket, T::Stream>), Error>[−]

Query this future to see if its value has become available, registering interest if it is not.

fn wait(self) -> Result<Self::Item, Self::Error>[−]

Block the current thread until this future is resolved.

fn map<F, U>(self, f: F) -> Map<Self, F> where
    F: FnOnce(Self::Item) -> U, [−]

Map this future's result to a different type, returning a new future of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F> where
    F: FnOnce(Self::Error) -> E, [−]

Map this future's error to a different error, returning a new future.

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

Map this future's error to any error implementing From for this future's Error, returning a new future.

fn then<F, B>(self, f: F) -> Then<Self, B, F> where
    B: IntoFuture,
    F: FnOnce(Result<Self::Item, Self::Error>) -> B, [−]

Chain on a computation for when a future finished, passing the result of the future to the provided closure f.

fn and_then<F, B>(self, f: F) -> AndThen<Self, B, F> where
    B: IntoFuture<Error = Self::Error>,
    F: FnOnce(Self::Item) -> B, [−]

Execute another future after this one has resolved successfully.

fn or_else<F, B>(self, f: F) -> OrElse<Self, B, F> where
    B: IntoFuture<Item = Self::Item>,
    F: FnOnce(Self::Error) -> B, [−]

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>, [−]

Waits for either one of two futures to complete.

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.

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.

fn join3<B, C>(
    self,
    b: B,
    c: C
) -> Join3<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future> where
    B: IntoFuture<Error = Self::Error>,
    C: IntoFuture<Error = Self::Error>, [−]

Same as join, but with more futures.

fn join4<B, C, D>(
    self,
    b: B,
    c: C,
    d: D

    <Self::Item as Stream>::Error == Self::Error, [−]

Flatten the execution of this future when the successful result of this future is a stream.

fn fuse(self) -> Fuse<Self>[−]

fn inspect<F>(self, f: F) -> Inspect<Self, F> where
    F: FnOnce(&Self::Item), [−]
