Why do we need Rust?

[elizarov]

To replace abomination of C++ for systems programming and actually make our systems safe.

[ValV]

And slow...

[ValV]

If I'm not mistaken, the hardest system code is done in C (even if it is not safe), not even C++

[ValV]

I saw benchmarks for C, C++, and Rust. Rust is slower than C++, which is slower than C

[Gerard Klijs]

I'd like to see those, I've seen where it slower, but only by a few percent, which is fine to trade in for more safety. And for some things not even C is powerful enough, so you'll need assembly, but rust let's you include assembly (but then it's not 100% anymore)

[ValV]

You're right. Just percents, but it almost always (always vs C) consume more memory 😁

[ValV]

I don't remember exactly, where I saw it, but this one looks familiar https://benchmarksgame-team.pages.debian.net/benchmarksgame/faster/rust.html

[Gerard Klijs]

And you don't have any memory leak in rust. I would rather see some real world examples instead of very small bits of code.

[ValV]

Yep, but we still write in old plain C. So why Rust is even less popular than FORTRAN?

[ValV]

I can assume that it's because of its speed and memory consumption + necessity to learn new syntax

[Dias]

because all those rankings are shit

[karelpeeters]

Why is Java more popular than Kotlin?

[karelpeeters]

Rankings don't correlate with benefits of the language.

[ValV]

But they measure it somehow

[karelpeeters]

Some weighted sum of questions on stackoverflow and searches on google usually.

[ValV]

So those rankings may correlate with a language difficulty + caused problems

[ValV]

Java on top
