![]() ![]() You have to enable mutability with let mut (special keyword for enabling modification of variables). Variables are immutable by default – once you set the value, you cannot modify it, which is something similar to const in JS.Variable type inference – it is here with the let keyword.Very strong typing is needed at the compile level, for instance you cannot just print numbers with println!(10).It comes with its own updater ( rustup ).Package manager – cargo – of course there’s a package manager like with any other language.The code is compiled to the machine level running on a bare OS, so no virtual machines or interpreters here. It has to be, otherwise it would be hard to justify a new language for system programming. The tests prove it’s even faster than Go and often even faster than C or C++ equivalents ( ), so the speed advantage is definitely there. Performance – Rust is considered to be “ blazing fast ”.Memory cleaning routines are added during the compile time and thus Rust delivers deterministic object removal from the memory (no GC pauses anymore) it looks like a perfect combination – you don’t have to do it yourself and it’s done automatically at the compile time. Garbage collection – there’s no runtime garbage collection such as in Java or C#, and.Instead of another intro to the language, I’ll like to share with you some interesting facts that are specific to Rust, assuming you know one of the application level C-derived languages such as Java, C#, JavaScript or C++. I recommend strongly visiting:Ĭurl -proto '=https' -tlsv1.2 -sSf | sh No, that’s not a good idea, as rustup will be missing. There are many workarounds and solutions for that, but Rust creators decided to break the legacy and do something from the ground up to prevent these types of attacks now and in the future. on billions of computers from large servers to the smallest intelligent sensors. It’s a nightmare for the majority of software that we use today and we use it everywhere. Memory problem fixĪbout 70%-80% of security related issues and programming errors are related to the management of memory.Ĭ language for instance, is very liberal when it comes to memory access, so we’ve got thousands of vulnerabilities related to buffer overflows, too easily accessing memory to read the secrets (passwords, tokens), injecting malicious code, etc. This means first of all, getting rid of the known problems with previous generations and delivering a fast modern language which is expected to become a language for tens of years to come like C, C++, and Java before it. Rust promises to be the representation of the next generation of languages. → To change or to pretend a change – that is the question The promise When building operating systems, servers, databases and applications that need to work very fast and minimize resource usage (such as web browsers on large computers or software for small underpowered IoT devices), system languages are being used. There are programming languages for business application programming such as Java, C#, Python, and Ruby, and programming languages used mostly for system level programming such as assembly language, C, and C++. However, in terms of popularity it’s far behind other languages, sometimes not even making it into the top 20.Īs of now, July 2020, it has moved from number 33 to 18 on the TIOBE index, so it may or may not improve in standing in the future. Stack overflow surveys always show Rust as the #1 loved language, every year since 2016. When reading the latest tech news it’s relatively easy to find a post about a big IT player embracing Rust or how Rust is loved by developers. ![]()
