dfhack_proto

This subcomponent of dfhack_remote contains all the generated code for interacting with DFHack remote API.

It contains two main modules:

• [messages] exposes the protobuf messages. This is the standard generated protobuf.
• [stubs] exposes the plugins and their RPC. DFHack is not using gRPC and this is a custom implementation

Internally these two modules are created under the generated module.

The terminology is based on gRPC: The stubs expose the feature from the plugin. They are built from a channel implementing the data exchange.

The code is regenerated under the condition that the environment variable DFHACK_REGEN is set.

This crates generates all its code directly in a source subfolder. It would likely be cleaner to use the $OUT_DIR, or macro to do this job.
