// Package protodesc provides functionality for converting
// FileDescriptorProto messages to/from protoreflect.FileDescriptor values.

// The google.protobuf.FileDescriptorProto is a protobuf message that describes
// the type information for a .proto file in a form that is easily serializable.
// The protoreflect.FileDescriptor is a more structured representation of
// the FileDescriptorProto message where references and remote dependencies
// can be directly followed.

// • Resolving the input or output message type for a service method.
