In 2026 the practical question is no longer &ldquo;can I write firmware in Rust?&rdquo; but &ldquo;which HAL do I write my driver against, and what breaks when the silicon vendor changes it?&rdquo; The three repositories that answer that question — <code>embedded-hal</code>, <code>esp-hal</code> and <code>rp-hal</code> — sit at different layers of the same stack, which is why comparing them as rivals misses the point and comparing them as collaborators is what actually ships products.</p>
