/**
Some libraries (such as handlebars or serde) offer functions that can generate data when given
an object that implements io::Write.

Some other libraries (such as Rocket) can consume data only from objects implementing io::Read.

Here is an example `piper` function that can be used to make these two kinds of libraries together.

[root@centos mysql]# nc -vz localhost 3306
nc: connect to localhost port 3306 (tcp) failed: Connection refused
Connection to localhost 3306 port [tcp/mysql] succeeded!


The reason is the first connection is against ::1 (IPv6), and the second to 127.0.0.1.
This could be seen with: tcpdump -i lo -n


[root@centos mysql]# grep localhost /etc/hosts
