no_std

Rust crates focused on embedded, bare metal and system programming
README.md

no-std-rs 🦀

Rust crates that run everywhere — #![no_std] first, std only when you ask for it. 🌍

From bare-metal embedded 🔌 to systems programming 🖥️: one crate, every target, no rewrites.

What we care about

  • 🚫 No hidden allocation — no_std by default; alloc and std behind opt-in features
  • 🧪 Amazing tests — unit, integration, property-based, miri-clean, and CI on real embedded targets
  • 📦 Small and honest — minimal deps, documented MSRV, semver taken seriously
  • 🤖 Robots welcome — AI-assisted PRs are fine here, as long as the tests prove it works
