According to Wikipedia, systems programming can be viewed as the category of software whose main purpose is to provide services to other software, operate in a constrained environment, or both. "Systems programming" is a somewhat vague and difficult to define term. Unlike C and C++, for example, it's impossible to compile Rust code that will produce a buffer overflow without explicitly opting into unsafe behavior. In particular, Rust strives for "type safety," meaning that the compiler enforces well-defined behavior for every Rust program. C and C++, although fast systems languages, are not safe. Rust has been described as a "fast, safe systems" language. When reading documentation, be sure to check the date. The 2018 release was a major milestone, particularly from the perspective of stability and backward-compatibility. This state of flux sometimes causes grief for newcomers because out-of-date documentation remains quite easy to find.Īlthough it will take time for this situation to resolve itself, help is on the way. The Rust Team uses an open governance model implemented through several groups drawing from members employed both inside and outside of Mozilla.ĭuring its fourteen-year history, the Rust language and tooling have undergone many changes. Shortly thereafter, the Mozilla Foundation became Rust's main sponsor. Mozilla got involved in 2009 once the language was mature enough to run basic tests and demonstrate its core concepts. Rust started as Graydon Hoare’s part-time side project in 2006 and remained so for over 3 years. It concludes by sketching the beginnings of a graph library in Rust. This article introduces Rust as a language that, although practically unknown today in cheminformatics, could one day play a role in the field. Rust is statically typed, but type inference means you'll omit most type annotations. Pure functional programming is possible with immutability enforced at compile time. Object-oriented programming is supported, but without classes. Gone is the garbage collector and runtime, but so is manual memory management. Platforms from embedded systems to Web browsers are well within reach. Performance matches C/C++ but with a distinctly modern feature set. But at the core lies something innovative and full of potential. These emerging languages can fly under the radar for many years due to the lack of scope and tooling, or due to frequent breaking changes. Newer languages are harder to evaluate because platforms, libraries, tooling, and stability take time to evolve.īut every decade or so a language comes along that tempts a critical mass of developers to try something new. For well-established languages, the choice is sometimes easy: JavaScript for client-side web development Python for machine learning and numerical analysis C/C++ for embedded systems and operating systems and Java for enterprise applications. The choice often boils down to four factors: maturity libraries platforms and tooling. Few decisions are more important in a software project than programming language.
