Also worth checking out libxev[1] by Mitchell Hashimoto. It’s a Zig based event loop (similar to libuv) inspired by Tigerbeetle’s implementation.

Also, the Zig 0.16.0 preview nightly builds includes a new Io library[0]. I have not used libxev or Tigerbeetles event loop, but I believe the standard Zig implementation is likely largely influenced by those two.
