High Performance, good error-checking: this is Why Rust is so popular

Rust occupied for some years now, always in the top positions in the lists of the fastest-growing programming languages on GitHub and Stackoverflow. For this popularity, there are good reasons for this.

Rust since 2006. The programming language comes from the keys of a Mozilla outsourcing developer. Since its Launch, the users based on the language – in the meantime, it finds application in the Building of web applications, Command-Line Tools, or distributed Services.

Low-Level language abstractions of Higher-Level languages

The Low-Level language, Rust is so efficient that it does not use automatic memory cleanup. However, it provides++, the Performance of C and C, but without the pitfalls, the developers at work need to know and be aware of.

The developers behind Rust wanted to create a language system programming safer and concurrency, i.e., the simultaneous execution of multiple calculations, instructions, or commands, easier. Both memory safety and concurrency errors occur when the Code accesses the data that it is not supposed to have access from time to time.

The Central concept: Ownership

The Rust achieved through its Central Feature, the so-called Ownership. Those who work with Rust, do not need to worry about but yourself, the Rust Compiler checks the static for you. This is also the reason why Rust works without a Garbage Collector (garbage collection) and you are on memory access error – you will need to unlike, for example, in C – not to Worry. Based on the concept of concurrency that means that you can work according to different paradigms. Message-Passing, shared State, Lock-Free or completely functional programming in Rust is possible. The Design of the programming language will help you to avoid common sources of error.

Concurrency in Rust

Messages are sent along a Channel whose Ownership is transferred. This allows it to send a Pointer from one to the other Thread without having to fear that the Threads try later, over this Pointer to access the memory. The Channels in Rust force isolated Threads. A Lock knows what data it protects. The data types in Rust, and to know if you may be sent between multiple Threads, and whether multiple Threads can safely access them – Rust’s Design forces, this safe use. You can even Stack Frames between the Threads share – Rust ensures that the Frames remain active, while other Threads can access it. All of these Benefits go back to Rust’s Ownership model. Locks, Channels, and data structures without Lock are defined outside of the core language libraries.

Focus on safety

The Rust Compiler is strict and safe storage administration, without Runtime Overhead. In General, Rust’s Lifetime Management has a strong focus on safety: The Thread-Safety in Rust is because of the mentioned reasons in comparison to other languages will be significantly higher. The concept of Safety Features, such as Sum-Types and the General immutability of the language taken into account.

Interesting Features and useful libraries

The language offers interesting Features like Cross-Compilation, Web-Assembly Targets for the front-end development, support for the development of mobile applications and some useful Libraries. Rust Code is read in comparison to Code in C++ is relatively easy to use. The language has functional Features such as map(), find() or filter(). Rust is a programming language with imperative Syntax. Higher-Order functions, you can still define.

TL;DR: Those who work with Rust, is forced to make memory allocation thoughts. Smart pointers and references is the base of Rust’s memory management are quasi. Those who come from C++, is likely to be able to incorporate relatively quickly. Who comes from Python, or JavaScript, probably needs a little longer to become familiar with the concepts. The resulting Code is more or less “clean by default”. In terms of the memory that you have with Rust very precise control with more safety compared to languages such as C.
