Why is everyone down on Rust? Seriously. I don't know it but I've considered learning it and it appeals to me and people literally scoff when I mention it. Saw it referred to as a meme language on Lemmy, which is built in Rust. What am I missing?
i think it’s mainly people being cranky and set in their ways. they got used to working around all the footguns/bad design decisions of the C/C++ specifications and really don’t want to feel like it was all for nothing. they’re comfortable with C/C++, and rust is new and uncomfortable. i think for some people, being a C/C++ developer is also a big part of their identity, and it might be uncomfortable to let that go.
i also think there’s a historical precedent for this kind of thing: when a new way of doing things emerges, many of the people who grew up doing it the old way get upset about it and refuse to accept that the new way might be an improvement.
Is Rust as close to the metal as C? Seems like there would still be a need for C. I could see Rust replacing Java as something that's so ceremonial and verbose, but from my limited perspective as a sometimes java dev, having only the most glancing experience with C, it seems like C would be hard to replace because of what it is. Buy I honestly don't know much about Rust either, I just think JS is so finicky and unpredictable whereas web assembly seems extremely fast and stable.
I mean, the simple proof is that Rust has been growing by leaps and bounds in the embedded world, which is the closest to bare metal you get. It’s also being used in the Linux kernel and Windows, and there are several projects building new kernels in pure Rust. So yeah, it’s safe to say that it’s as close to the metal as C.
Also, the comparison to Java is understandable if you’ve only been exposed to Rust by the memes, but it doesn’t hold up in practice. Rust has a lot more syntax than C (although that’s not saying much), but it’s one of the most expressive languages on the market today.
