This repo provides reflection APIs for protocol buffers (also known as "protobufs" for short)
and GRPC. The core of reflection in protobufs is the
descriptor.
A descriptor is itself a protobuf message that describes a .proto source file or any element
therein. So a collection of descriptors can describe an entire schema of protobuf types, including
RPC services.

The desc package herein introduces a Descriptor interface and implementations of it that
correspond to each of the descriptor types. These new types are effectively smart wrappers around
the generated protobuf types
that make them much more useful and easier to use.
import "github.com/jhump/protoreflect/grpcreflect"
The grpcreflect package provides an easy-to-use client for the
GRPC reflection service,
making it much easier to query for and work with the schemas of remote services.
import "github.com/jhump/protoreflect/dynamic"
import "github.com/jhump/protoreflect/dynamic/grpcdynamic"
The dynamic package provides a dynamic message implementation. It implements proto.Message but
is backed by a message descriptor and a map of fields->values, instead of a generated struct. There
is also sub-package named grpcdynamic, which provides a dynamic stub implementation. The stub can
be used to issue RPC methods using method descriptors instead of generated client interfaces.
