Have there been any follow-ups on this topic? I'm using multicast UDP socket as well (in fact, published `mdns-sd` crate) and would love to see `std::net` supports SO_REUSEADDR at least...

@jnordwick > @keepsimple1 What were you needing to use `SO_REUSEADDR` for UDP? You can use `SO_REUSEPORT` (but still not possible in `std::net` as you are trying to fix already). Actually...

“非型” 怎么样？ 表达了不会有的意思。谐音的飞听着也不错 :)

我知道了, 谢谢。先前没有看到 bottom type wiki page 里面提到的 In Rust, the bottom type is called never type. 我个人觉得， 可以说： * 「非类型」是类型系统里的一种「底类型」 我的经验是， 长期来看， 中文文言文的单字常常可以比现代汉语的词语更加好用。
