/// note: in epoll, a tcp connection failure is indicated by EPOLLERR + EPOLLHUP, though just EPOLLERR is enough to indicate a connection failure.
/// EPOLLHUP may happen when we haven't event called `connect` on the socket, but it is still a valid event to check for.

///
/// ```
/// fn main() -> std::io::Result<()> {
