does socket2 support select?

[keepsimple1]

Is there any support of select (as in Unix) or something similar?

Not in socket2, I would consider it out of scope for socket2. However if you're looking for something like epoll/kqueue you can consider Mio.

socket2 already depends on libc and winapi, thus has the tools needed to support something like select. In fact, the poll_connect function seems to do something similar, on windows and on Unix.

I know and I felt that was out of scope already, but the std lib's TcpSocketalso had it, so we decided in the end to add it back again. But select is really out of scope for socket2.

I understand that. On the other hand, it seems to me that Rust net/socket ecosystem fragmented too much. The std::net is missing lots of important features, while 3rd-party crates are overlapping each other and often times we have to pull in a new dependency to just call a single common function.

It's not socket2's fault. But I am worried that the situation hurts the productivity of many Rust users. The ideal case is that std::net can be fixed to cover all the bases, but I don't know if that will ever happen. Sorry for ranting.
