Hey everyone,i'm quite new to Rust and also such low level programming in generalI've made a simple client and server based chat application, as a project for my networking class: https://github.com/SaharshSamir/rust_chatI showed this to my professor and he wants some acknowledgement to the client that their message was delivered. I can't seem to figure out how i would implement that.
Full code for reference: https://github.com/Jorissss/adventofcode22/blob/b8cead1b5c222a02a506cbbf6c98966bfdeb3759/day2/src/main.rs
I have a packed generational arena data structure I actually use for these situations as well, which allows me to remove values without worrying about indices going invalid.
rustfmt is the official formatter.
People with a lot more money and resources than the Mozilla foundation have been trying to do that, because they have giant C++ codebases which they can't afford to rewrite, possibly ever. Google to name but one. asan, tsan, msan, ubsan are literally google projects, and their internal code style is know to be rather draconian.
And yet even they have become rust-curious with seemingly good results, as well as consider literally writing their own C++ compatible language.
That seems like a shortcoming of the unused code check more than anything else. The unused code check is best-effort and is not guaranteed to catch all cases. I did a quick test on my computer and I don't get an unused code warning even when the trait isn't implemented at all. Here's a related tracking issue.
