Future for the join function.

Join3

Future for the join3 function.

Join4

Future for the join4 function.

Join5

Future for the join5 function.

Lazy

Future for the lazy function.

Map

Future for the map method.

NeverError

Future for the never_error combinator.

OptionFuture

A future representing a value which may or may not be present.

Pending

Future for the pending() function.

Functions

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.

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.

pending

Creates a future which never resolves, representing a computation that never finishes.

poll_fn

Creates a new future wrapping around a function returning Poll.

ready

Create a future that is immediately ready with a value.

select

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