Query a binary format (BSON, CBOR, MessagePack, UBJSON)

[davidglavas]

Is it possible to serialize a json document as, say, a BSON document and then extract fields out of the BSON document directly?

For example, the mongodb c++ driver offers functions for getting fields out of BSON documents. Is there something similar?

Right now, you first need to parse the binary value before you can access a specific value:

auto j = json::from_bson(x);
auto v = j["my_key"];
