Rust is another compiling language that may replace the position of C/C++ in server filed.

It runs fast and can be written easily comparing with Python/Go. Python is a dynamic language

and is limited in GIL, while Go is limited in its GC. That is reason why I prefer to learning Rust.

1.Rust macro:

If we add `!` affter a callee function, we call on a macro. And it is normal function when we call

without `!`.

println!("Hello World")
