serialization

问题 So i'm legit confused. It won't compile for an external serialization function. It gives the error cereal could not find any output serialization functions for the provided type and archive combination. So the code below doesn't compile #include <fstream> #include <glm/glm.hpp> #include "SceneObject.h" #include <cereal/cereal.hpp> #include <cereal/archives/json.hpp> template<typename Archive> void serialize(Archive& archive, glm::vec3& v3) { archive(cereal::make_nvp("x", v3.x), cereal::make

问题 I am trying to serialize a large (~10**6 rows, each with ~20 values) list, to be used later by myself (so pickle's lack of safety isn't a concern). Each row of the list is a tuple of values, derived from some SQL database. So far, I have seen datetime.datetime , strings, integers, and NoneType, but I might eventually have to support additional data types. For serialization, I've considered pickle (cPickle), json, and plain text - but only pickle saves the type information: json can't

问题 I have written following fbs file namespace testing; table polygon { x : double; y : double; } table layer { layer_name : string; polygons : [polygon]; } root_type layer; My plan is to serialize approx 5 Million coordinates and dump it into one file. Problem is what I see is the number of bytes is increased compared to what I was expecting. I am expecting it should be arounf (5M* 16) bytes. But the size what I am getting is 140000032 bytes Here is the java code which I am using for dumping

问题 See updates at the bottom -- A similar question was asked here, but never resolved: pickling and unpickling user-defined class I'm working on a project which necessitates pickling user defined classes, and sending them to a remote server where they are unpickled and called. We use the Dill library to accomplish this, and have had a lot of success. Unfortunately, I've run into an issue I'm having a hard time debugging. I create and pickle a class as follows: import dill, base64 import time,

问题 I have a flattened JSON: { "CaseName" : "John Doe v. State", "CaseDate" : "<some date>", "Client.FirstName" : "John", "Client.LastName" : "Doe", "Client.Email" : "johndoe@gmail.com" etc... } I want to deserialize it back to this entity: public class Case() { public string CaseName { get; set; } public string CaseDate { get; set; } public Client Client { get; set; } } where Client.FirstName , Client.LastName , and Client.Email are properties in the Client object. Using Json.NET, is there any
