Rust hello world

By following official [1]

• Step 1:

We have a new folder named hello-rust and it has the following structure

• Step 2: go to the hello-rust folder and run the code

Bingo, it works!

• What is inside of main.rs?

quit simple, just println, should be short for printline. Looks like a combination of python and C++? fn is similar to def in python. There is no return type which is required by C++.

• Check the folder content

This time, we got bunch of compiled files in the target folder, even some debug files. It is pretty interesting.

Let’s explore more next time!
