I'm neither praising or admonishing rust.
Did you read the parent comment or its parents' comment I was responding to at all?
reply(grandparent comment): "Cloudflare crashed a chunk of the internet with a rust app a month or so ago"
The actual bug had nothing to do with rust, yet rust is specifically brought up here.
(grandparent comment): "Rust isn’t a panacea, it’s a programming language. It’s ok that it’s flawed, all languages are."
No Rust programmer thinks it's a panacea! Rust has never advertised itself this way.
The cloudflare bug was the equivalent of an uncaught exception caused by a malformed config file. There's no recovery from a malformed config file - the software couldn't possibly have done its job. What's salient is that they were using an alternative to exceptions, because people were told exceptions were error-prone, and using this thing instead would make it easier to write bug-free code. But don't do the equivalent of not catching them!
replyAnd then, it turned out to not really be any better than exceptions.
Most Rust evangelism is like this. "In Rust you do X and this makes your code have fewer bugs!" Well no it doesn't. Manually propagating exceptions still makes the program crash and requires more typing, and doesn't emit a stack trace.
That was why I brought it up. I wasn't trying to be snarky or haughty. Thank you for filling in the gaps, I should have done that instead of the 1-liner.
