ruby-nio4r - 2.5.8-3 main

nio4r (New IO for Ruby) provides an abstract, cross-platform stateful
I/O selector API for Ruby. I/O selectors are the heart of
"reactor"-based event loops, and monitor multiple I/O objects for
various types of readiness, e.g. ready for reading or writing.
.
The most similar API provided by Ruby today is Kernel.select, however
the select API requires you to pass in arrays of all of the I/O
objects you're interested in every time. nio4r provides a more
object-oriented API that lets you register I/O objects with a selector
then handle them when they're selected for various types of events.
.
nio4r is modeled after the Java NIO API, but simplified for
ease-of-use.
.
Its goals are:
.
* Expose high-level interfaces for stateful IO selectors.
* Keep the API small to maximize both portability and performance across
many different OSes and Ruby VMs.
* Provide inherently thread-safe facilities for working with IO objects.
