这个问题是在《形单影只的 Socket》最后留的问题，这里给出一个思路供大家参考，看下那篇文章再来看这个效果可能会更好。

传送门：测试环境：Ubuntu 14.04 好了，进入正题。首先构造一个 TCP 连接，这里使用形单影只的 socket 来启动一个 echo server

$ nc -vp 11111 localhost 11111
Connection to localhost 11111 port [tcp/*] succeeded!

$ ss -ap | grep 11111

Async/Await - The challenges besides syntax - Cancellation

This is the second article in a series of articles around Rusts new async/await feature. The first article about interfaces can be found here.

In this part of the series we want to a look at a mechanism which behaves very different in Rust than in all other languages which feature async/await support. This mechanism is Cancellation.

`ld` – Wading through Mac OS X linker hell

Intro

Friend: I tried looking at static linking in Mac OS X and it seems nearly impossible. Take a look at this http://stackoverflow.com/a/3801032

Me: I have no idea what that -static flag does, but I'm pretty sure that's not how you link to a library. Let me RTFM a bit.
