In plain words
Ferrum.js is a JavaScript library that brings Rust-inspired programming patterns to JavaScript, focusing on traits and advanced iteration capabilities. It enables developers to write more robust and expressive code by implementing functional programming concepts similar to Rust's type system. The library is designed for JavaScript developers who want to incorporate Rust-style abstractions and iteration methods into their projects without leaving the JavaScript ecosystem.

Unbug – Rust macros for programmatically invoking breakpoints2024 · github.com · ▲96This 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.

Talanoa▲340Hi 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…
