# The parallel\Events class

## The Event Loop

The Event loop monitors the state of sets of futures and or channels (targets) in order to perform read (`parallel\Future::value`, `parallel\Channel::recv`) and write (`parallel\Channel::send`) operations as the targets become available and the operations may be performed without blocking the event loop.
