Specifically in the Linux kernel, the 2 big reasons to use it are memory safety (huuuuggee benefit) and that a lot of younger devs like it and thus it will attract their contributions.
The only reasons I can think of to not use it are that some people want their own toolchain and having multiple languages in the kernel adds complication. But tbh, none of that justifies banning Rust stuff that realistically wouldn’t have been written at all if C were the only option.
And then there’s the people who show up in Phoronix, HN, Reddit, and YouTube comments saying Rust is over-hyped without showing why it’s unfit for purpose and also trying to dictate what someone does with their own project. Perhaps it’s something to do with the representation of queer people and other minorities in the Rust community, because otherwise I do not understand why people would be sooo passionate in hating the Rust community like the group I described above is.
Water makes the curls coherent, everything else makes them incoherent, a reminder that entropy always increases. Also that makes it frizzy.
