Codegen your problems away - device-driver toolkit
summary
Codegen tool that converts a YAML/DSL input into a Rust driver via a compiler-like proc‑macro pipeline, producing about 18,000 lines generated from a 2,100‑line spec (≈9× code savings). It models registers, commands and buffers, supports endianness and field conversions, exposes platform IO via a read/write trait, and ships with 97 tests and a documented 1.0 released Dec. Missing: multi‑register batch ops and dynamic‑length commands blocked by current const‑generic limits.
