Detailed Description

Functions for protobuf message to/from struct conversion.

Conversion functions rely on user-defined functions with the following signatures:

1. StructType ReadProtoStruct(proto_structs::io::ReadContext&, / proto_structs::io::To<StructType>, / const MessageType&)

   2. `void WriteProtoStruct(proto_structs::io::WriteContext&,
   

   / const StructType&, / MessageType&) @iverbatim This functions should be foundable by ADL lookup (just place them in the namespace whereStructType` is defined).

It is recommended to define WriteProtoStruct function as template with a StructType parameter and use universal reference StructType&& as a second parameter to enable perfect forwarding for conversions.
