uvw VS libev

Compare uvw vs libev and see what are their differences.

uvw

Header-only, event based, tiny and easy to use libuv wrapper in modern C++ - now available as also shared/static library! (by skypjack)

libev

Full-featured high-performance event loop loosely modelled after libevent (by enki)

    Thank you for this.

    I am interested in how concurrency can be represented elegantly and efficiently, so I am interested in how libraries can simplify async and make it easier to reason about and write

    The libev and ioring support is great for IO scalability (https://github.com/enki/libev not sure if this is the official repo)

    In Python I use the "select" module and use epoll on Linux.

    I am currently thinking of designing an API that allows the registration of epoll-like listeners to arbitrary objects, including business objects, so you can efficiently register a listener on multiple behaviours of multiple arbitrary objects.

    I wrote an async/await simulation in Java and my scheduler is really simple, it's just a for loop that checks to see if there are any tasks that can progress. I notice the switch_fiber in polyphony must do something similar. This is similar to a yield in a coroutine.

    My async/await simulation takes the following program:

      task1:

    It's done even now. See ev.h where they do this. Just that you disable GCC's aliasing warning. There's a reason why restrict and aliasing became important to deal with. It wasn't standards that killed it.

What are some alternatives?
