Nov 2, 2022 · Rust is what's known as a “memory-safe” language because it's designed to make it impossible for a program to pull unintended data from a computer's memory accidentally.
More accurately, Rust contains both a safe and unsafe programming language. Rust can be thought of as a combination of two programming languages: Safe Rust and Unsafe Rust. Conveniently, these names mean exactly what they say: Safe Rust is Safe. Unsafe Rust is, well, not.
Rust is a multi-paradigm, general-purpose programming language that emphasizes performance, type safety, and concurrency. It enforces memory safety —meaning that all references point to valid memory—without a garbage collector.
Feb 14, 2023 · When the coder discussion board Stack Overflow conducts its annual poll of developers around the world, Rust has been rated the most “loved” programming language for seven years running. Even...

Rust started as a Mozilla research project partly meant to reimplement key components of the Firefox browser. A few key reasons drove that decision: Firefox deserved to make better use of modern, multicore processors; and the sheer ubiquity of web browsers means they need to be safe to use. But those benefits are needed by all software, not just br...
Rust code compiles to native machine code across multiple platforms. Binaries are self-contained, with no external runtime apart from what the OS might provide, and the generated code is meant to perform as well as comparable code written in C or C++.
Rust won’t compile programs that attempt unsafe memory usage. Most memory errors are discovered when a program is running. Rust’s syntax and language metaphors ensure that common memory-related problems in other languages—null or dangling pointers, data races, and so on—never make it into production. The compiler flags those issues and forces them ...
Rust controls memory management via strict rules. Rust’s memory-management system is expressed in the language’s syntax through a metaphor called ownership. Any given value in the language can be “owned,” or held and manipulated, only by a single variable at a time. Every bit of memory in a Rust program is tracked and released automatically through...
Rust lets you live dangerously if you need to, to a point. Rust’s safeties can be partly suspended where you need to manipulate memory directly, such as dereferencing a raw pointer à la C/C++. The key word is partly, because Rust’s memory safety operations can never be completely disabled. Even then, you almost never have to take off the seatbelts ...
None of Rust’s safety and integrity features add up to much if they aren’t used. That’s why Rust’s developers and community have tried to make the language as useful and welcoming as possible to newcomers. Everything needed to produce Rust binaries comes in the same package. External compilers, like GCC, are needed only if you are compiling other c...
Rust works on all three major platforms: Linux, Windows, and MacOS. Others are supported beyond those three. If you want to cross-compile, or produce binaries for a different architecture or platform than the one you’re currently running, little additional work is involved, but one of Rust’s general missions is to minimize the amount of heavy lifti...
Few developers want to start work in a new language if they find it has fewer, or weaker, features than the ones they’re used to. Rust’s native language features compare favorably to what languages like C++ have: Macros, generics, pattern matching, and composition (via “traits”) are all first-class citizens in Rust. Some features found in other lan...
One part of Rust’s larger mission is to encourage C and C++ developers to use Rust instead of those languages whenever possible. But C and C++ users expect to have a decent standard library—they want to be able to use containers, collections, and iterators, perform string manipulations, manage processes and threading, perform network and file I/O, ...
One measure of a language’s utility is how much can be done with it thanks to third parties. Cargo, the official repository for Rust libraries (called “crates”) lists some 60,000-plus crates. A healthy number of them are API bindings to common libraries or frameworks, so Rust can be used as a viable language option with those frameworks. However, t...
Dec 12, 2022 · According to the Stack Overflow Developer Survey 2022, Rust has been the most-loved language for seven straight years. Rust boasts a unique security model, which promises memory safety and concurrency safety, while providing the performance of C/C++.
Mar 18, 2022 · Now that we understand how important programming safety is, let’s see why Rust is one of the safest languages and how it avoids most of the security issues we normally encounter with languages like C/C++. For those not familiar, Rust is a high-level multi-paradigm language.
