|Summary : represent an operation awaiting completion
|Description : |
A \'Future\' object represents an operation that is currently in progress, or
has recently completed. It can be used in a variety of ways to manage the
flow of control, and data, through an asynchronous program.
Some futures represent a single operation and are explicitly marked as
ready by calling the \'done\' or \'fail\' methods. These are called \"leaf\"
futures here, and are returned by the \'new\' constructor.
Other futures represent a collection of sub-tasks, and are implicitly
marked as ready depending on the readiness of their component futures as
required. These are called \"convergent\" futures here as they converge
control and data-flow back into one place. These are the ones returned by
the various \'wait_*\' and \'need_*\' constructors.
It is intended that library functions that perform asynchronous operations
would use future objects to represent outstanding operations, and allow
their calling programs to control or wait for these operations to complete.
The implementation and the user of such an interface would typically make
use of different methods on the class. The methods below are documented in
two sections; those of interest to each side of the interface.
It should be noted however, that this module does not in any way provide an
actual mechanism for performing this asynchronous activity; it merely
provides a way to create objects that can be used for control and data flow
around those operations. It allows such code to be written in a neater,
forward-reading manner, and simplifies many common patterns that are often
involved in such situations.
See also Future::Utils which contains useful loop-constructing functions,
to run a future-returning function repeatedly in a loop.
Unless otherwise noted, the following methods require at least version
