Great work on capnp! I'm getting a really smooth ride writing code that uses it.
A question - is there any way to truncate pre-allocated ::capnp::List? I don't mind, that it would leave empty space in the message at the end of the list. Along the lines: ... myList @0 : List(myType) ... // preallocate auto myList = builder.initMyList(max_count); // set count elements // ... // myList.truncateToSize(count) I understand that there is an approach of creating an intermediate list, along these lines: capnp::Orphanage orphanage; std::vector<capnp::Orphan<MyType>> orphans; auto my = orphanage.newOrphan<MyType>(); // Set fields of my // ... orphans.push_back(kj::mv(o)); myList.initOp(orphans.size()); int i=0;for(auto it = orphans.begin(); it != ops.end(); ++it, ++i) sr.getOp().adoptWithCaveats(i, std::move(*it)); But what I want, seems to be a lot simpler, doesn't need extra copy, etc. Just adjust the size field, to truncate the list!
