Rust Programming LanguageRust Programming Language

Rust is a programming language for writing highly reliable and performant software. Rust takes the best of C++, and uses the type system to help you write code that’s free of bugs. It does this in three ways:

  • ensures that integer values are never used for floating point operations;
  • enforces memory safety and control; and 
  • offers various guarantees about valid data. 

The Rust programming language was designed by Mozilla as an alternative to the C++ programming language, as C++ taught the world much misery. Library developers who have used C++ have complained that it’s difficult to get errors out of their code due to the poor error reporting and poor exception handling abilities. The language which eventually took its place: Rust. Read more on Rust programming language to understand it in detail.

Elaborating On The Design Of Rust

Concurrency, efficiency, and security are the three core goals of Rust programming language. The emphasis is on reliability for applications performing I/O or resource intensive tasks or that need guaranteed resource releases in a concurrent application. As such, there is an emphasis on being thread safe and not making assumptions about resource availability from the thread management system.

Its design also emphasizes safety over performance, with an emphasis on preventing data corruption by tracking potentially unsafe operations to improve the safety of programs that use mutable data structures. It can be built using a number of different approaches, including garbage collection and manual memory management. To further read more on Rust programming language, one has to understand how it helps its users. So let’s dive into it.

How Does Rust Programming Language Help Its Users?

The focus on systems programming means that it has a syntax closer to C but without the complexity of C++ templates or boilerplate. It offers familiar features such as block statements, structured control flow statements, and higher-order functions but with a distinct type system that helps to ensure that values are passed correctly and cannot be used for incorrect purposes (e.g. using integer values where floating point values are expected).

The Rust programming language also intends to leverage its type system to enforce interface matching and ownership rules, making it a sound system. Rust is ineffective until it has been compiled into a native binary. Rust’s emphasis on the programmer is evident in its syntax and core-libraries. Rust uses a simple procedural syntax similar to C, but with support for generic functions and types. Rust achieves this without macros or templates by using multiple match statements (first-class functions). Additionally, the language has operators that look like function calls (e.g., codice_1), which also improves readability. Rust’s standard library is not based on templates and cannot be extended through inheritance or adding more base classes. It avoids complex C++-style syntax and is designed to avoid the need for any macros. It is usually very similar in spirit to an equivalent Python library.

Wrapping Up

Upon reading more on Rust programming language, you must have understood that it implements a strict type system to enforce memory safety, allowing stronger memory discipline than C++. Also, it offers features that are common in other systems programming languages (e.g., iterators, parallel processing, collections) but with higher performance than they can achieve in those environments. It uses the same syntax as C, but provides generic packages for types and functions. Also, it allows programmers to use data structures without worrying about their internal representation (e.g., whether it is an array or linked list). It is  a language based on the same roots as C, but with enhanced types and pattern matching.
