Hey HN, I find myself reaching for tools like it-tools.tech or other random sites every now and then during development or debugging. So, I built a toolkit with a sane and simple CLI interface for most of those tools. For the curious and lazy, at the moment, ut has tools for, - Encoding: base64 (encode, decode), url (encode, decode) - Hashing: md5, sha1, sha224, sha256, sha384, sha512 - Data Generation: uuid (v1, v3, v4, v5), token, lorem, random - Text Processing: case (lower, upper, camel, title, constant, header, sentence, snake), pretty-print, diff - Development Tools: calc, json…

I wrote libcorrect in C in 2016 and wanted to revisit it in Rust. Instead of doing just a direct conversion, I went down the rabbit hole of making Rust's std::simd work for me. I ended up with a templated, generic Viterbi decoder for convolutional codes that dispatches the decode at runtime depending on which instruction sets are available. For small rates and orders, the entire decode lives in registers. Larger codes work through memory but take advantage of some acceleration structures. I also spent some time building a tool to find optimal (max d_free) conv codes for a given rate and…

Serialization framework with some interesting numbers: 10-20x faster on nested objects than json/protobuf. Technical approach: compile-time codegen (no reflection), compact binary protocol with meta-packing, little-endian layout optimized for modern CPUs. Unique features that other fast serializers don't have: - Cross-language without IDL files (Rust ↔ Python/Java/Go) - Trait object serialization (Box) - Automatic circular reference handling - Schema evolution without coordination Happy to discuss design trade-offs. Benchmarks:…

An 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…

This project is inspired by some of the asserts in Unreal engine. Due to reliance on core_intrinsics it is necessary to develop using nightly Rust, but there are stubs in place so a production build will not require nightly. I recently released version 0.2 which includes no_std support and adds optional log message arguments to the ensure macro.

Wrote this to learn more about the `chumsky` parser combinator library, rustyline, and the `ariadne` error reporting crate. Such a nice DX combo for writing new languages. Still a work in progress, but I thought I'd share :)

I've created cppmatch, a lightweight, header-only C++ library that brings Rust-inspired pattern matching and error handling to C++. It tries to imitate the functionality of the questionmark (?) operator in C++ by using a macro that uses the gcc extension https://gcc.gnu.org/onlinedocs/gcc/Statement-Exprs.html This allows to create exceptionless code with non-intrusive error-as-value that unlike Exceptions, makes it clear which kinds of error a function can generate and forces you to handle (or ignore) them. The ? operator translates to *expect* To handle the errors I…

Hi community, we just released https://github.com/tonbo-io/typed-arrow. When working with arrow-rs, we noticed that schemas are declared at runtime. This often leads to runtime errors and makes development less safe. typed-arrow takes a different approach: - Schemas are declared at compile time with Rust’s type system. - This eliminates runtime schema errors. - And introduces no runtime overhead — everything is checked and generated by the compiler. If you’ve run into Arrow runtime schema issues, and your schema is stable (not defined or switched at runtime), this project…

Hey HN! We’ve just open-sourced model2vec-rs, a Rust crate for loading and running Model2Vec static embedding models with zero Python dependency. This allows you to embed text at (very) high throughput; for example, in a Rust-based microservice or CLI tool. This can be used for semantic search, retrieval, RAG, or any other text embedding usecase. Main Features: - Rust-native inference: Load any Model2Vec model from Hugging Face or your local path with StaticModel::from_pretrained(...). - Tiny footprint: The crate itself is only ~1.7 mb, with embedding models between 7 and 30 mb. Performance:…
