Oh, wait a minute, you were doing from json, not to json.
Try this on for size. It converts from a std.json.JSONValue
to a std.variant.Varaint, which is quite a bit simpler to use.
======
import std.variant;
import std.json;
Variant jsonToVariant(string json) {
auto decoded = parseJSON(json);
return jsonValueToVariant(decoded);
}
Variant jsonValueToVariant(JSONValue v) {
Variant ret;
final switch(v.type) {
case JSON_TYPE.STRING:
ret = v.str;
break;
case JSON_TYPE.INTEGER:
ret = v.integer;
break;
case JSON_TYPE.FLOAT:
ret = v.floating;
break;
case JSON_TYPE.OBJECT:
Variant[string] obj;
foreach(k, val; v.object) {
obj[k] = jsonValueToVariant(val);
}
ret = obj;
break;
case JSON_TYPE.ARRAY:
Variant[] arr;
foreach(i; v.array) {
arr ~= jsonValueToVariant(i);
}
ret = arr;
break;
case JSON_TYPE.TRUE:
ret = true;
break;
case JSON_TYPE.FALSE:
ret = false;
break;
case JSON_TYPE.NULL:
ret = null;
break;
}
return ret;
}
