Hello! Is there any library to easily do RPC from a host to a embeded target? Like anything close or far from:

* on target side:
    * integrate the lib so that it exposes an interface for RPC calls to arrive,
    * annotate some functions with an attribute macro so they are made available to the RPC API (and put some metadata in the binary);
* on host side:
    * define the available APIs (like a macro that takes an elf to parse data for instance),
    * init the interface,
    * call the target functions seamlessly.
