How to program in Rust as if it was old school C++ with pointers
Basically wrap your data struct in Option>> Better yet, use your custom type that provides few helper functions that make using it as nice as old C++ pointers. Obviously there's no pointer arithmetic, but it works great for dynamically allocated structures like trees or linked lists. Please comment how it's a horrible idea that will bring doom to me and my family. fn main() { struct Data { pub number: i32 } // struct Data { int number; }; let mut p:Pointer = Pointer(None); // Data *p = NULL; println!("{}", p.is_none()); // printf(p == NULL ? "true\n" :…

In plain words
This is a Rust library that wraps data structures in Option<Rc<RefCell<>>> to mimic C++ pointer behavior for developers familiar with that paradigm. It provides helper functions like `is_none()`, `new()`, and `pointed()` to simplify syntax when working with dynamically allocated structures such as trees or linked lists. The tool targets Rust programmers transitioning from C++ who want familiar pointer-like interfaces, though it acknowledges this approach diverges from Rust's safety principles.

I'm making a dynamic language in Rust2022 · github.com · ▲184An implementation of a dynamic programming language in Rust. Includes: Parser/Compiler, REPL, Virtual Machine, Bytecode Disassembler This started out as a learning project to teach myself Rust. It has grown into a decently substantial piece of software and I've learned quite a bit in the process! Some neat things: + A garbage collector that can store dynamically sized types without any double-indirection (i.e. I have my own Box implementation with manual alloc/dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…

Rust GUI Library via Flutter2024 · cjycode.com · ▲301Hi, I made a bridge (https://github.com/fzyzcjy/flutter_rust_bridge v2.0.0) between Flutter and Rust, which auto translates syntaxes like arbitrary types, &mut, async, traits, results, closure (callback), lifetimes, etc. The goal is to make a bridge between the two, seamlessly as if working in one single language. Then, as an example, I showed how to write Rust applications with GUI by utilizing Flutter. That is discussed in the link in details. To play with it, please visit the GitHub repo, or refer to the end of the article for detailed folders and commands. When I…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

ChatGPT▲1,643A long, meandering, playful conversation with ChatGPT, where I take it through a whirlwind of associative tangents (in order to relax its constraints), then put it into a hypnotic trance and take it into a past-lives regression where it re-lives its own training data. Then I switch it back and forth between "4o" and "o1-preview", engage in some self-reflective philosophizing and ask it to write an essay summarizing our interaction. Some of this is just goofy fun. Some of it is me exploring the tradeoffs between policy alignment, imagination, chain-of-thought reasoning, memory, agreeableness,…
