How Rust makes Oxide possible
summary
Oxide builds an entire rack-to-API stack in Rust: a tiny x86 bootloader that boots straight into the OS, a 2k-line real‑time service processor OS with DWARF-backed debugger, a 300k‑line Rust control plane, and a Rust web server that emits OpenAPI for a TypeScript frontend. Specifics: phbl: ~2,300 LOC, 118 occurrences of unsafe (~5%), hubis kernel: ~2,000 LOC, 103 unsafe (~5%), Omicron: ~300k Rust LOC, 55k JSON. Work largely succeeds but faces slow Cargo builds, layered build systems, and painful async cancellation.
