<h3>Module: queue
</h3>
<div class="description summary">
<p>The Queue module adds a common data structure for FIFO operations. In its
simplest form, it is little more than an array wrapper. Additional
submodules introduce more functionality such as promotion and removal of
queued items.</p>
<p>An AsyncQueue class is provided in the queue-run submodule. This class
affords a mechanism to do complex sequential and iterative callback
execution across configured timeouts.
