o1heap VS lfjson

Compare o1heap vs lfjson and see what are their differences.

o1heap

Constant-complexity deterministic memory allocator (heap) for hard real-time high-integrity embedded systems. There is very little activity because the project is finished and does not require further changes. (by pavel-kirienko)

  • [Study Project] A memory-optimized JSON data structure
    4 projects | /r/cpp | 23 Oct 2022
    https://github.com/gaujay/lfjson Your mandatory bi-weekly JSON news is here! JK, but let's cut to the chase: this is actually not a new JSON serializer. I wanted to explore some allocator-related topics and noticed (almost) all JSON libraries put emphasis on speed, not memory usage (like in this article).

What are some alternatives?

memory - STL compatible C++ memory allocator library using a new RawAllocator concept that is similar to an Allocator but easier to use and write.

glaze - Extremely fast, in memory, JSON and interface library for modern C++

fprime - F´ - A flight software and embedded systems framework

json - JSON for Modern C++

real-time-cpp - Source code for the book Real-Time C++, by Christopher Kormanyos
