Let's get started with the Rust language. Before going into detail about Rust programming, it is important to consider why we need it, bearing in mind we already have several other languages such as Java, C/C++, and Python. In C/C++/C# we have a lot of control over the hardware that we are running on, so we can optimize it properly. In C/C++/C# languages, we can have more control, as we can translate them directly to assembly code, but they are not very safe, as small mistakes can create big segfaults. On the other hand, we have the Python and Ruby languages, which give us more safety, but very little control over what's going on. This is where Rust comes into play. Using Rust, we have all the control, plus all the safety as well.

Rust is a systems programming language, which means you can utilize some interesting features such as fine-grained control over allocation or its not-required garbage collection (memory leaks are rare) or minimal runtime. Rust runs blazingly fast, which makes this language everyone's favorite, as you can run and compile your code very quickly. It can provides us better performance than C/C++. Rust prevents almost all crashes and segfaults. It's just safe by default. It has no null pointers and no dangling pointers, it's just a sophisticated type and the last part is that it eliminates data races, which means it guarantees thread safety and ownership.
