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
Future for the
and_then combinator, chaining a computation onto the end of
another future which completes successfully.Future for the
catch_unwind combinator.A future which takes a list of futures and resolves with a vector of the
completed values.
A future representing a value that is immediately ready.
A future which is never resolved.
A future representing a value that is immediately ready.
Errors returned from the
Spawn::spawn function.A future representing a value that is immediately ready.
A future representing a value that is immediately ready.
Future for the
flatten combinator, flattening a future-of-a-future to get just
the result of the final future.Future for the
flatten_stream combinator, flattening a
future-of-a-stream to get just the result of the final stream as a stream.Future for the
from_err combinator, changing the error type of a future.A future which “fuses” a future once it’s been resolved.
A future representing a value that is immediately ready.
Do something with the item of a future, passing it on.
Future that forwards one element from the underlying future
(whether it is success of error) and emits EOF after that.
Future for the
join combinator, waiting for two futures to
complete.Future for the
join3 combinator, waiting for three futures to
complete.Future for the
join4 combinator, waiting for four futures to
complete.Future for the
join5 combinator, waiting for five futures to
complete.A future which takes a list of futures and resolves with a vector of the
completed values.
A future which defers creation of the actual future until a callback is
scheduled.
A future implementing a tail-recursive loop.
Future for the
map combinator, changing the type of a future.Future for the
map_err combinator, changing the error type of a future.A future representing a value that is immediately ready.
Future for the
or_else combinator, chaining a computation onto the end of
a future which fails with an error.A future which adapts a function returning
Poll.Future for the
select combinator, waiting for one of two futures to
complete.Future for the
select2 combinator, waiting for one of two differently-typed
futures to complete.Future for the
select_all combinator, waiting for one of any of a list of
futures to complete.Future yielded as the second result in a
Select future.Future for the
select_ok combinator, waiting for one of any of a list of
futures to successfully complete. Unlike select_all, this future ignores all
but the last error, if there are any.A future that is cloneable and can be polled in multiple threads.
Use
Future::shared() method to convert any future into a Shared future.A wrapped error of the original future that is cloneable and implements Deref
for ease of use.
A wrapped item of the original future that is cloneable and implements Deref
for ease of use.
Future for the
then combinator, chaining computations on the end of
another future regardless of its outcome.Enums
Combines two different futures yielding the same item and error
types into a single type.
Kinds of errors that can be returned from the
Execute::spawn function.The status of a
loop_fn loop.Traits
A trait for types which can spawn fresh futures.
Trait for types which are a placeholder of a value that may become
available at some later point in time.
Asynchronous conversion from a type
T.Class of types which can be converted into a future.
Functions
Creates a future which represents a collection of the results of the futures
given.
Creates a new “leaf future” which will resolve with the given result.
Creates a future which never resolves, representing a computation that never
finishes.
Creates a “leaf future” from an immediate value of a failed computation.
Creates a “leaf future” from an immediate value of a failed computation.
Creates a “leaf future” from an immediate value of a finished and
successful computation.
Creates a future which represents a collection of the results of the futures
given.
Creates a new future which will eventually be the same as the one created
by the closure provided.
Creates a new future implementing a tail-recursive loop.
Creates a “leaf future” from an immediate value of a finished and
successful computation.
Creates a new future wrapping around a function returning
Poll.Creates a new “leaf future” which will resolve with the given result.
Creates a new future which will select over a list of futures.
Creates a new future which will select the first successful future over a list of futures.
