Code is compiling, but at run time, it crash with error:
terminate called after throwing an instance of "std::logic_error"
what(): Serializer not found for type 1A
(abort core dumped)

my testcase codes:
main.cpp
object.h
object.cpp

So, not sure it is an issue, it try to understand how i should use serialization from hps fr inherited class, but maybe i failed to understand well.

I can deserialize int member of a structure from a char array, but not double member (equals to 0)

If I convert the char buffer to string and then use from_string, it works!

Hi,

Cheers,

hi, i have initialized a unordered_map<int, unordered_map<int, string> > and i have inserted values into it. now from the examples given i can write it to a file using 'to_stream()' like this...
std::ofstream out_file("data.log", std::ofstream::binary); //lets say data.log is the filename
hps::to_stream(data, out_file);
Now how can reconstruct the map from this file stream ????
I would be really great if you could help me with this one.
Thanks

Hi again,
I'm searching how to implement class template Serializer for embed private/protected local variable from an ancestor class ?
If i have an abstract ancestor parent class of an other one who has private variables, i not find how to access these variable for serialize/parse.
Could you provide a little example of code for i can learn how to do that with hps please ?
(happy new year also)

object.h

From boost serialize example, i see it is possible to implement class objects (intrusive method) for archive private methods. So maybe there is a way in the same intrusive code methods with hps... but i actuallt failed by use friend class hps::Serializer then implement class inside other class...

hps::to_string() method fails to serialize a struct with enum class member as it complain no serialize method found inside enum class.

Is there a way to serialize/deserialize structs with enum fields ?

Left open as a reminder for myself, as well as anyone interested in working on it.

We are trying to serialize a class with your great library but clang++ compiler outputs following error messages,

In file included from ./hps/src/hps.h:6:
In file included from ./hps/src/basic_type/basic_type.h:4:

  static void serialize(const T& t, B& buf) { t.serialize(buf); }
                                              ~ ^
./hps/src/buffer/string_output_buffer.h:46:40: note: in instantiation of member function 'hps::Serializer<std::variant<std::vector<std::byte, std::allocator<std::byte> >, std::__cxx11::basic_string<char> >, hps::StringOutputBuffer, void>::serialize' requested here
    Serializer<T, StringOutputBuffer>::serialize(t, *this);
                                       ^

Here is the class,

class message
{
    public:
    
    std::string id;
    int status;
    std::variant<std::vector<std::byte>, std::string> body;

    template <class B>
    void serialize(B &buf) const
    {
        buf << id << status << body;
    }

    template <class B>
    void parse(B &buf)
    {
        buf >> id >> status >> body;
    }
};

Thanks for the hard work on building such a good library, but GPL3 makes it difficult to work with (in cases of me, I've been in a search for header only serialization libs in C++, for my own game engine specifically which I don't want to open source yet). Is it possible to provide another license such as Apache/BSD/ZLIB etc?

I compile the example offered by this repo，and it runs right. But I found that the string/file is not readable, it is messy code, so I want to know if there is a way to as data in string/file readablely. thanks

Do you know if there is a project which aim to port hps, with a common binary specification, to js, java, or other language?

Hi,
https://github.com/alphaonex86/CatchChallenger/blob/master/server/base/BaseServer.cpp#L296
Give me 65536, HPS bug? how debug?
Cheers,

Hi. it is ok

Hi, im currently working in a project in which im using your library.
Im facing some difficulty in serializing a class with has a object pointer to another seperate class.
In this example (link) geeks for geeks code, how do i serialize using the hps library ??

https://www.geeksforgeeks.org/b-tree-set-1-insert-2/

is there any chance we can add support for python numpy array (which is actually implemented in c)? or any hints on how to do that would be much appreciated,
