Futures

This module contains a number of functions for working with Futures, including the FutureExt trait which adds methods to Future types.

Structs

AbortHandle	A handle to a `Abortable` future.
AbortRegistration	A registration handle for a `Abortable` future. Values of this type can be acquired from `AbortHandle::new` and are used in calls to `Abortable::new`.
Abortable	A future which can be remotely short-circuited using an `AbortHandle`.
Aborted	Indicator that the `Abortable` future was aborted.
CatchUnwind	Future for the `catch_unwind` method.
Empty	Future for the `empty` function.
Flatten	Future for the `flatten` method.
FlattenStream	Stream for the `flatten_stream` method.
Fuse	Future for the `fuse` method.
Inspect	Future for the `inspect` method.
IntoStream	Stream for the `into_stream` method.
Join	Future for the `join` function.
Join3	Future for the `join3` function.
Join4	Future for the `join4` function.
Join5	Future for the `join5` function.
JoinAll	Future for the `join_all` function.
Lazy	Future for the `lazy` function.
Map	Future for the `map` method.
OptionFuture	A future representing a value which may or may not be present.
PollFn	Future for the `poll_fn` function.
Ready	Future for the `ready` function.
Remote	A future which sends its output to the corresponding `RemoteHandle`. Created by `remote_handle`.
RemoteHandle	The handle to a remote future returned by `remote_handle`.
Shared	Future for the `shared` method.
Then	Future for the `then` method.
UnitError	Future for the `unit_error` combinator, turning a `Future` into a `TryFuture`.

A future that may have completed.

An extension trait for Futures that provides a variety of convenient adapters.

abortable	Creates a new `Abortable` future and a `AbortHandle` which can be used to stop it.
empty	Creates a future which never resolves, representing a computation that never finishes.
err	Create a future that is immediately ready with an error value.
join	Joins the result of two futures, waiting for them both to complete.
join3	Same as `join`, but with more futures.
join4	Same as `join`, but with more futures.
join5	Same as `join`, but with more futures.
join_all	Creates a future which represents a collection of the outputs of the futures given.
lazy	Creates a new future that allows delayed execution of a closure.
maybe_done	Wraps a future into a `MaybeDone`
ok	Create a future that is immediately ready with a success value.
poll_fn	Creates a new future wrapping around a function returning `Poll`.
ready	Create a future that is immediately ready with a value.
