Query your Rust codebase and generate types for anything

Hello HN! As a long-time professional Rust developer. I've always been frustrated by the difficulty and "hackiness" of producing bindings to other languages, whether a frontend, an FFI library, etc. Not just in Rust but in any language. After many years of trying existing solutions and trying to make my own, I've finally developed a solution I'm very happy with. RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum's `.route`, function definitions, and more, and then receive rich type information including all argument types,…

What it does

Rust Type Kit (beta) - query your Rust codebase and generate types for everything - reachingforthejack/rtk

RTK is a tool for querying Rust codebases to extract accurate type information and emit types in other programming languages. Examples and the Lua API can be found in the examples directory and the Lua API definition file . RTK is in early development. Documentation is limited, and certain features such as generic parameters and extended standard types may be incomplete. Review the generated Lua API in lua/rtk_api.lua for the most accurate reference. Contributions are encouraged; the codebase is fairly slim and approachable for new contributors. cd < my-project > touch < script_name > .lua Use the examples/axum-to-ts/rtk.lua file as a reference template. Ensure the Lua script specifies the…from github.com

  • Hsrs – Type-Safe Haskell Bindings Generator for RustMay 2026 · github.com · ▲53

    Hey everyone! I've been working on hsrs, a type-safe Haskell Bindings Generator for Rust. I couldn't really find any bindings generator that would create type-safe, rich bindings for Haskell from Rust. Naturally, both languages have rich type systems, so I was amazed that no awesome bindings generator already existed, hence I decided to write my own. hsrs feels very similar to pyo3 and napi-rs, and if you've used those, hsrs will feel right at home. What's unique about hsrs as opposed to hs-bindgen is that it has type-safe bindings for rich types, like Result, Maybe, etc. while also…

  • Rust GUI Library via Flutter2024 · cjycode.com · ▲301

    Hi, I made a bridge (https:&#x2F;&#x2F;github.com&#x2F;fzyzcjy&#x2F;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…

  • I'm making a dynamic language in Rust2022 · github.com · ▲184

    An implementation of a dynamic programming language in Rust. Includes: Parser&#x2F;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&#x2F;dealloc) + The smart pointer used to reference GCed data is a thin pointer. The ptr metadata needed for DSTs is stored in…

  • An opinionated and statically-typed TypeScript SDK generator2022 · easysdk.xyz · ▲81

    Hi Hacker News! My name is Sagar, I’m working on a startup called Speakeasy - we’re making all APIs self-service. The platform is currently in beta, but we’re independently launching this tool which you can use to generate language-idiomatic, statically-typed TS SDKs from any public OpenAPI schemas. We hope to continue iterating on this to give devs a way to easily generate high fidelity client SDKs for all the major languages. Inspiration for this product is from past experiences struggling with OpenAPI. I was originally optimistic about using the OpenAPI tools to build out our offering,…

  • Shelgon: A Framework for Building Interactive REPL Shells in Rust2025 · github.com · ▲130

    I've been working on Shelgon, a framework that lets you build your own custom REPL shells and interactive CLI applications in Rust. You can use Shelgon to: - Create a custom shell with only a few lines of code - Build interactive debugging tools with persistent state between commands - Develop domain-specific language interpreters with shell-like interfaces - Add REPL capabilities to existing applications Getting started is straightforward - implement a single trait that handles your command execution logic, and Shelgon takes care of the terminal UI, input handling, and async runtime…

  • Hacker News API SDKs → Code Generation in Rust2023 · hacker-news.sideko.dev · ▲39

    Hi Hacker News! Patrick and Elias here. We built an SDK &#x2F; Documentation generator for REST APIs. The link included shows the shiny output of our system: the docs! We generated 5 SDKs and docs from the Hacker News OpenAPI we found on GitHub. If you write code in Python, Typescript, Go, Ruby, or Rust, we’d love for you to try an SDK out! If you want to generate SDKs for your own API try our tool here: https:&#x2F;&#x2F;github.com&#x2F;Sideko-Inc&#x2F;sideko We are both software engineers, and we built this tool because we were spending too much time writing API integrations, supporting…

  • Talanoa▲343

    Hi 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…

    Hey HN! Pilots everywhere are required to keep a logbook of all their flying hours, aircraft, airports, and so on. Since I track everything digitally (some people still just use paper logbooks!), I put together some data visualizations and a few 3D globes to show my flying history. This globe is probably my favourite so far: https:&#x2F;&#x2F;jameshard.ing&#x2F;pilot&#x2F;globes&#x2F;all If you’ve got ideas for other graphs or ways to show this kind of data, I’d love to hear them!

  • I was the main contributor to workout.lol, an open-source fitness app to easily build a workout routine. The project had traction (1.4k GitHub stars, 95 forks, ~20K visits&#x2F;month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
