RUST: THE TOUGH PART - Learning Rust

Hi Guys,

I’m a Web Developer who is just learning Rust. This is the third post I wrote about Learning Rust(https://medium.com/learning-rust) on Medium.

Also I am from Sri Lanka and not a native english speaker. So this can have some grammar mistakes. Please correct me if you found any kind of mistake, even in grammar, even in the previous posts :) Thanks.
