Asynchronous 'gRPC' Client and Server Runtime R package rgrpc version 0.1.1 A first-class asynchronous 'gRPC' <https://grpc.io/> runtime built on the generic asynchronous 'C++' API ('GenericStub', 'AsyncGenericService') <https://grpc.github.io/grpc/cpp/>. Requests and responses cross the native boundary as method names plus opaque byte buffers; 'RProtoBuf' supplies and consumes the bytes, so schemas are loaded at runtime and no generated service stubs are required. Native completion threads never call the R API: completions are queued natively and delivered in batches on the R main thread. Complements 'RProtoBuf' rather than replacing it. Links against the system 'gRPC' library for 'C++'.
