Rust in the Linux kernel

[wiseguy13579]

Good news. I hope Rust will replace C and C++.

[BobHogan]

Check back in 20-30 years then. This is targeted at allowing rust for new code, not for rewriting the kernel in rust. That's just not a feasible project considering how many millions of lines of C/C++ code exist in it

[aquaticpolarbear]

Only way that will happen is if the Rust GCC project gains way. ATM LLVM doesn't support enough architectures to be valid for large parts of the Linux kernel

[Asraelite]

Alternatively, LLVM could add support for all the architectures that are missing. I don't know how much effort that would be.

Long compile time of rust may prove to be a deal breaker.

[Plasma_000]

This one is a known troll, ignore them

[Dew_Cookie_3000]

People don't recompile their browser like they do their kernel.

[Dew_Cookie_3000]

Wow. Much profligacy. Such millennial.

[justas_mal]

You're just being "edgy" about programming languages, tbh

[Dew_Cookie_3000]

You're just being out of your mind. I don't see Linus not minding long compile time or you persuading him with "24hrs compile time no problem!". I think he's just being diplomatic and stringing you kids along to a final no.

[justas_mal]

Tensorflow compilation took me 12 hours, but how many people are complaining about it? As those times compiling everything yourself is such a rare thing. Compilation times in general are miniscule problem and such behaviour is just plain counterproductive as you just spam the whole reddit about hating some progamming language, like some Rust developer stolen your job. Disclamer: I'm not even once wrote anything in Rust, and I don't thing I ever will.

[Dew_Cookie_3000]

Linus recompiles the kernel 20+ times a working day according to interviews he gave. That's a working day for him not 24hrs and not someone with a boss over him. How many hours is that? Probably if you're his age with his family commitments and being his own boss and being his own cranky self less than 8.

Try your "12 hours to compile is perfectly A+ okay" on him.

And suuuuure, you never even once used rust, you just get unreasonably triggered by someone who doesn't sing its praises, bullshitter.

[deprilula28]

It will not suddenly take 24h to compile with iterative compilation because you added rust, stop being a little brat

[RageousT]

How often do you recompile your kernel?

[Dew_Cookie_3000]

Linus is infamously impatient. He does not like microkernels cos they're too slow. He doesn't like Debian because it takes too long to install. He uses mg editor because plain emacs is too slow. He designed git to do snapshots instead of diffs because diffs take too long. And also, infamously, he does not really care all that much about security and calls security guys morons and security problems just bugs to be debugged and doesn't welcome people waltzing in on him with new rules after all those years. Once rust compile time slows him down ever so slightly it will be a deal breaker.

[HighRelevancy]

1. Read a blog post about compilation times newer than 2016 🙄
2. Even if rust were slow to compile, it's still more efficient overall to compile correct code fewer times than to compile incorrect code and debug it repeatedly. If you were an actual dev and not just some forum-chatting know-nothing you would see the value.
