![]() ![]() ![]() That's how I execute it and get the the printed message. I have created a simple program to print a statement because printing "hello world" is too mainstream. You can use dnf install rust and get started with Rust. Owned values can be borrowed in Rust to allow usage for a certain period of time. ![]() Variables are moved to new locations, preventing the previous location from using it. Two Key concepts which eliminate data races. What elimination of data races does is that it simply assures the developer can't write the wrong parallel code. Nowadays, we have computers with tons of cores and many threads running in parallel but it's really tough to write parallel code. One of very important features of Rust is it eliminates data races. Rust, like JS, Ruby, and Python, is safe by default which means you can't have segfaults, dangling pointers or null pointers. In a lot of areas, Rust can do better than C/C++. Rust runs blazing fast since Rust is a compile language with LLVM as it's back-end and it taps in to a large suite of optimizations. What it implies is, the developer is guaranteed the performance of the code and also, anyone who knows C/C++ can understand and reason with a Rust code. It has a minimal runtime and it's very close to the bare metal. Garbage collector is not required anymore. Well, Rust is a systems programming language like C/C++ but unlike those, what it gives to the developers is fine grained control over memory allocations. It gives the developer all the safety and the control. And somewhere in the middle, there's Java and a few others which are a good mixture of both, with control over the hardware they run on and vulnerabilities that don't show up much. It’s not limited to just gaming though, and can be used as the basis of an operating system, file system, or to write browser components. It’s the smart choice for applications that use Virtual Reality to build a simulation. They can't get segfaults, you can get exceptions but they are pretty contained. WHY USE IT: 1 I Am Speed: Rust’s speed makes it a pretty good candidate for developers looking to create a game engine. On the other hand, we have languages like Python, Ruby, and JS where the developer has very little control over what's going on but they are very safe. However, this is not very safe it's easier to segfault or to cause security bugs like heartbleed. We have often seen this spectrum where we have C/C++ which has more control of the hardware which it's running on, enabling the developer to optimize the performance by executing finer control over the assembly generated. Most people, now, might wonder exactly why do you need another programming language, when we already have a lot of them. Rust is a systems programming language which runs blazing fast, prevents almost all crashes, segfaults and data races. ![]()
