iogrpc

C23 gRPC runtime scaffold for the ioplane ecosystem.

The planned architecture keeps HTTP/2 transport and io_uring ownership in iohttp; iogrpc owns gRPC framing, metadata, status, deadlines, cancellation, flow control, protobuf-c codec boundaries, and service dispatch. The runtime is intended to expose a pure C ABI. C++ is limited to isolated protoc host tooling.

Current status

This repository is at the bootstrap/scaffold stage. The source, public headers, tests, examples, and code generator are not implemented yet. Do not interpret the CMake source list as a built feature.

The implementation plan is docs/plan/2026-08-06-iogrpc-plan.md.

Planned build workflow

Build and test inside the Podman development container:

podman build -t iogrpc-dev:latest -f deploy/podman/Containerfile .
podman run --rm -it -v "$(pwd):/workspace:Z" iogrpc-dev:latest
cmake --preset clang-debug
cmake --build --preset clang-debug
ctest --preset clang-debug
