Something that deteriorates the structural integrity of load-bearing frameworks /s.

Being serious, it's another programming languages that is gaining popularity. Others can expand on why it's good. I've never used it myself so I can't comment in good faith. I also don't have any experience with Rust-bros so I can't comment on their code quality. I've mostly just been watching amused as they fight with the Linux development community.

Iron Oxide. Everyone else is wrong.

It's a brutally competitive and toxic game.

It's a programming language, which is particularly relevant for Linux, because it doesn't require a runtime (separate program that runs the code). This allows it to be used in the kernel.

But it also means that it's very good for building libraries. With a small bit of extra work, virtually any other programming language can call libraries implemented in Rust (like you can with libraries implemented in C).
Add to that, that Rust allows for performance similar to C and makes lots of typical C bugs impossible, and suddenly you've got folks rewriting all kinds of C libraries and applications in Rust, which is something you might have also heard about.

Actual answer:

Rust is a relatively new programming language. Similar to C or C++ it compiles directly into executable binary code so it can be used for bare metal or low level operating system programming. It is thus relevant to Linux kernel development as things like drivers can and are being developed in Rust.

Compare this to the likes of Java or C# which get compiled to bytecode or a kind of pseudo machine code that gets run in a virtual machine, which has advantages for application development, or something like Python which is interpreted (or just-in-time compiled) at run-time, useful as an end user scripting language.

Rust is designed from the ground up to tackle some modern problems, a key one being memory safety. It's a lot more paranoid about memory allocation and access and it's structured around this. Older languages like C allow the programmer a lot more absolute control over the hardware, which effectively means the C programmer has a lot more footguns in his toolbox. Theoretically, Rust offers fewer opportunities for the developer to shoot himself in the foot.

Rust also comes with some really cool tooling. Compiler errors usually point straight at the problem and say something like "Shouldn't there be a colon here?" The build system, called Cargo, is really slick in a lot of ways, handling linking, compiling, even library package management in a very automatic fashion. It's real slick to work with.

As with anything, fans of the language can be a bit much; they stereotypically suggest rewriting everything under the sun in Rust whether it makes sense or not, and this includes the Linux kernel, which has caused some friction in the community; Linux contributors are often very accustomed to C and some don't want to deal with anything else.

Rust is a programming language designed to run on crabs. It just happens to also run on computers. When rust programmers talk about the borrow checker, that's something born directly out of having to run on crabs. It's difficult to get the little guys to cooperate otherwise. And when they talk about rust having good error messages that's because of the crabs too. The compiler is not just some piece of software, it's a piece of software being run on crabs and the crabs have some measure of intuition to them. Basically what I'm saying is that carcinization applies to computer hardware.

The bane of Intel CPUs, and a trigger word for C geriatrics.

It’s a 2025 movie, starring Alec Baldwin, that gained notoriety in 2021, when a cinematographer was accidentally killed by a live round fired from a prop-revolver that Alex Baldwin was using.

Rust is both a nice programming language, and an obnoxious social movement made of a small minority of Rust programmers who are very loud

It's a cult.

It's a survival crafting game where players help each other survive the world with mutual cooperation, kind words and absolutely no Nazi or racist behaviour.

It’s also what this beautiful thing is written in

step one get hrt prescription

step two learn rust

step three buy socks

a low level language that has really nice features when compared to c and c++, but honestly i find it difficult to read. probably my lack of experience with it, tho.

A type of person whos apartment would be a mess cause they never collect their garbage, but they have a good memory where they put things and what they need, so it is never a problem.

Programming language like many others It has some fancy borrow checker that makes memory usage get statically analyzed by the compiler, so you dont have to manually manage memory, and the program won't need a garbage collector

It's for programmers who need their Imposter Syndrome amplified.
