Starting with v0.7.1 Mio will do the same as we're no longer checking 32 bit iOS/macOS on our CI.
epoll(2)‘s EPOLLERR event as Event::is_write_closed if it’s the only event (https://github.com/tokio-rs/mio/commit/0c77b5712d675eeb9bd43928b5dd7d22b2c7ac0c).SO_NOSIGPIPE on all sockets (not just UDP) on for Apple targets (https://github.com/tokio-rs/mio/commit/b8bbdcb0d3236f4c4acb257996d42a88dc9987d9).POLL_ABORT on Windows (https://github.com/tokio-rs/mio/commit/a98da62b3ed1eeed1770aaca12f46d647e4fa749).SIO_BASE_HANDLE calls on Windows (https://github.com/tokio-rs/mio/commit/b15fc18458a79ef8a51f73effa92548650f4e5dc).accept4(2) (https://github.com/tokio-rs/mio/commit/4e306addc7144f2e02a7e8397c220b179a006a19).lazy_static on Windows (https://github.com/tokio-rs/mio/commit/57e4c2a8ac153bc7bb87829e22cf0a21e3927e8a).Version 0.7 of Mio contains various major changes compared to version 0.6. Overall a large number of API changes have been made to reduce the complexity of the implementation and remove overhead where possible.
Please refer to the blog post about 0.7-alpha.1 for additional information.

Instead Poll::poll will now return an error if one occurs.From<usize> is removed from Token, the internal field is still public, so Token(my_token) can still be used.Poll and registered event sources. It is recommended to reread the documentation of at least event::Source and Poll.Event was changed to be a wrapper around the OS event. This means it can be significantly larger on some OSes.Ready was removed and replaced with various is_* methods on Event. For example instead checking for readable readiness using Event::ready().is_readable(), you would call Event::is_readable().Ready::is_hup was removed in favour of Event::is_read_closed and Event::is_write_closed.Events was changed to return &Event.Evented was renamed to event::Source and now takes mutable reference to the source.os-oll feature. To enable the network types use tcp, udp and/or uds.
