[capnproto] initialise nested lists

['Frank' via Cap'n Proto]

Hi,


I use Capnproto to serialise data. What is the best way to fill
nestedList and list from std::vector<std::vector<bool>> resp.
std::vector<bool>? For list I used initList() and the set() method in a
loop but I am not sure how to proceed with nestedList. Do I have to
create kj::Arrays for the nested lists?

--
struct Name {
nestedList @0 :List(List(Bool));
list @1 :List(Bool);
}

Best,

Frank

Hi Frank,

I think you want something like:

auto outer = name.initNestedList(vec.size());
for (uint i = 0; i < vec.size(); i++) {
auto inner = outer.init(i, vec[i].size());
for (uint j = 0; j < vec[i].size(); j++) {
inner.set(j, vec[i][j]);
}
}

Hi Kenton,

auto outer = name.initNestedList(vec.size());
for (uint i = 0; i < vec.size(); i++) {
auto inner = outer.init(i, vec[i].size());
for (uint j = 0; j < vec[i].size(); j++) {
inner.set(j, vec[i][j]);
}
}

works like a charm. Thank you very much!
