Installation

To use this library, simply download and include the header file Streamable.hpp into your project or use NuGet to install it.

Features

• fast - fast^2, memory-- and easy++ compared to MsgPack
• easy-to-use - inherit a class and use a macro :D
• single-header - just copy paste the file into your project
• has no dependencies - uses the C++20 standard library and OS native API for best performance
• cross-platform -

Platform	Support	Details
Windows	Yes
macOS	Partial	No UTF16 encoding for memory--
Linux	Partial	No UTF16 encoding for memory--

• supports every data type - beside itself (so called "streamables"), raw/smart pointers (ex:. std::unique_ptr, std::shared_ptr etc...), most STL classes (std::tuple, std::optional, std::variant etc...), any nested range (ex.: std::wstring, std::map, std::vector<std::list> etc...), PODs (ex.: POD structs and classes, enums, etc...), primitive types (ex.: bool, unsigned int, double etc...)

Usage

1. Inherit from the IStreamable class or any class that implements it.
2. Use the macro STREAMABLE_DEFINE and pass your class and the objects you want to parse
3. OPTIONAL For (de)serialization of inherited classes use STREAMABLE_DEFINE_BASE and pass the classes
4. OPTIONAL If "streamables" pointers are (de)serialized you MUST implement FindDerivedStreamable (if you forget this, don't worry, a static_assert will scream :O )

Benchmark

This benchmark contains anything from trivial types to maps of strings to STL containers to vectors of derived classes as base class pointers etc...

Library	Time (ms)	Memory Usage (KB)
Streamable	0.379	85
nlohmann::json	2.9	187
MsgPack	0.755	87

Downsides and Limitations

While Streamable offers many benefits, it's essential to consider its limitations as well:

• Custom Format - it has a custom but simple format for storing the data
• Programming Language - supports only C++ >= 20
