Products that do what Query your Rust codebase and generate types for anything does

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,…

   Tysm, a Rust crate for using ChatGPT with Structured Outputs▲7

   Hi HN! This Christmas I made `tysm`, a rust crates which simplifies using ChatGPT with Structured Outputs. Essentially you just tell it the rust type you want the output to conform to, and it handles creating the JSON Schema, passing it to ChatGPT's chat-completions API, and deserializing the response. Structured Outputs are very useful because they guarantee that the response will conform to whatever type you expect. I'm already finding my crate very useful since I love using Structured Outputs but I hate writing JSON Schemas myself. Technical details for rust heads: To generate the JSON…

   I built an open-source Rust/TS AI agent runtime with a Next.js-style DX▲5

   Link: https://docs.trysoma.ai/ For the past ~9 months I’ve been building Soma, an open-source AI agent & workflow runtime written in Rust, with a TypeScript SDK (Python coming soon). It’s not a framework; it’s meant to sit underneath whatever agent/tooling code you already write (Vercel AI SDK, LangChain, custom code, etc.). It provides features around your framework + a better DX for building agents. I’ve tried to take a Next.JS model: open-source, good DX, self-deployable. I originally set out to build a vertical back-office/operations product for SMEs. I needed a…

   Topaz – A small application language that compiles through Rust▲5

   Hi HN, I'm Matt, CTO at STUDIO HAZE in Seoul. I've wanted to build a programming language for twenty years, ever since Ruby got me wondering what a small language out of Korea might look like. Today I'm opening the repo for the first time, as Topaz v5.2. Topaz reads like Python or TypeScript, runs on a reference interpreter (topaz run), and builds a self-contained native binary by lowering to Rust, then handing off to the Rust toolchain (topaz build). function factorial(n: int) -> int { if n string { return "안녕하세요, {이름}님!" } print(인사하기("토파즈")) // 안녕하세요, 토파즈님! sql, sh, and path…

    Rust vs. Go – What are your thoughts?▲10

    I personally haven't event used or looked at Rust so I don't have an opinion. So now I'm interested hearing what others think? I think the syntax of Rust isn't very appealing, but that's not a good reason to /not/ look at it. Convince me? :)

    gline-rs – an inference engine for GLiNER models, in Rust▲5

    Hi everyone, wanted to share about gline-rs, an inference engine for GLiNER models written in Rust. This family of lightweight language models proved to be efficient at zero-shot Named Entity Recognition (NER) and other tasks such as Relation Extraction, while consuming less resources than large generative models (LLMs). This implementation has been written from the ground up in Rust, and supports both span- and token-oriented variants (for inference only). The goal is to provide a production-grade and user-friendly API in a modern and safe programming language, including a clean and…

    Jobsearch – unified CLI for scraping job boards▲5

    Author here. Got tired of checking Upwork, NoFluffJobs, eFinancialCareers, LinkedIn and HN threads separately, so I built a CLI that scrapes them into a local SQLite DB and lets me browse everything in one web UI with filters and semantic search. Details: - Scraping via real browser over CDP (your own logged-in session, no API keys) - Embeddings run locally (nomic-embed-text via fastembed), stored in Lance - Rust backend, SolidJS frontend embedded in binary, single static executable Works for my use case (Europe-based contractor). It's my first rust project, decided to do local CLI, it's…

    SSVM – Speed up your Node.js apps with Rust and WebAssembly▲5

    Raw performance (the lack of) is always a contentious point for JavaScript, especially in our post-Moore era of computing. Node.js gets around this issue through extensive of use of native libraries and modules written in C, including the V8 JS engine itself. But as application developers, how do YOU create high performance functions? Write in C and run as a NAPI module? Write in Rust and run as a V8 wasm? Well, there is another (better and faster) way now! The SSVM is a fully featured WebAssembly VM that is optimized for server-side applications.…

    Gochan – A library of channel architectures for Go, inspired by Rust▲5

    Hi All, I felt like I was re-inventing the wheel by bolting similar channel architectures onto different Go structs repeatedly so I decided to extract some common types into into one library so that they would be easier to re-use: - oneshot - spsc - spmc - mpsc - mpmc - broadcast - watch The types are inspired by Rust channels so if you're coming from Rust they should feel familiar. So far I'm really enjoying using them but it'd be great to get some external feedback if you have time! https://github.com/amorey/gochan Andres

    Rust-loguru – A flexible Rust logging library like Python's Loguru▲5

    I've just released rust-loguru, a logging library for Rust that aims to combine intuitive API design (inspired by Go/Python's Loguru) with Rust's performance characteristics. Some highlights: - Consistently outperforms the standard log crate by 50-80% in benchmarks. - Multiple log levels and an extensible handler system -File rotation with better performance than log4rs and other alternatives - Error handling utilities and context helpers I built this because I wanted a logger that was both ergonomic to use and high-performance. The benchmarks comparing it to slog, log, and tracing are…
