[−][src]Module futures::future
Futures
This module contains the Future
trait and a number of adaptors for this
trait. See the crate docs, and the docs for Future
, for full detail.
Structs
AndThen | Future for the |
CatchUnwind | Future for the |
Empty | A future which is never resolved. |
ExecuteError | Errors returned from the |
Flatten | Future for the |
FlattenStream | Future for the |
FromErr | Future for the |
Fuse | A future which "fuses" a future once it's been resolved. |
FutureResult | A future representing a value that is immediately ready. |
Inspect | Do something with the item of a future, passing it on. |
IntoStream | Future that forwards one element from the underlying future (whether it is success of error) and emits EOF after that. |
Join | Future for the |
Join3 | Future for the |
Join4 | Future for the |
Join5 | Future for the |
JoinAll | A future which takes a list of futures and resolves with a vector of the completed values. |
Lazy | A future which defers creation of the actual future until a callback is scheduled. |
LoopFn | A future implementing a tail-recursive loop. |
Map | Future for the |
MapErr | Future for the |
OrElse | Future for the |
PollFn | A future which adapts a function returning |
Select | Future for the |
Select2 | Future for the |
SelectAll | Future for the |
SelectNext | Future yielded as the second result in a |
SelectOk | Future for the |
Shared | A future that is cloneable and can be polled in multiple threads.
Use |
SharedError | A wrapped error of the original future that is cloneable and implements Deref for ease of use. |
SharedItem | A wrapped item of the original future that is cloneable and implements Deref for ease of use. |
Then | Future for the |
Enums
Either | Combines two different futures yielding the same item and error types into a single type. |
ExecuteErrorKind | Kinds of errors that can be returned from the |
Loop | The status of a |
Traits
Executor | A trait for types which can spawn fresh futures. |
Future | Trait for types which are a placeholder of a value that may become available at some later point in time. |
FutureFrom | Asynchronous conversion from a type |
IntoFuture | Class of types which can be converted into a future. |
Functions
empty | Creates a future which never resolves, representing a computation that never finishes. |
err | Creates a "leaf future" from an immediate value of a failed computation. |
join_all | Creates a future which represents a collection of the results of the futures given. |
lazy | Creates a new future which will eventually be the same as the one created by the closure provided. |
loop_fn | Creates a new future implementing a tail-recursive loop. |
ok | Creates a "leaf future" from an immediate value of a finished and successful computation. |
poll_fn | Creates a new future wrapping around a function returning |
result | Creates a new "leaf future" which will resolve with the given result. |
select_all | Creates a new future which will select over a list of futures. |
select_ok | Creates a new future which will select the first successful future over a list of futures. |
