How It Works

1
🔍 Discover the toolbox

You stumble upon this free collection of smart storage tools built from scratch for C++ programs while looking for ways to make apps remember data faster.

2
📖 Explore the options

You read about different clever ways to store and quickly grab the most important or recently used pieces of information, like special memory keepers.

3
⭐ Pick a memory keeper

You choose one like the recent-use keeper because it automatically prioritizes the data you touch most often, keeping everything speedy.

4
📁 Add it to your work

You simply place the ready-to-use files into your own project folder, no fuss needed.

5
🧪 Give it a quick test

You follow the easy examples to store some sample data and fetch it back, watching it handle limits perfectly.

6
⚡ See the speed magic

Your program now grabs data lightning-fast without slowing down, even as it fills up.

✅ Fast storage achieved

Congratulations, your app now has reliable, efficient memory that works smoothly every time, ready for more features ahead.

What is cpp-from-scratch?

This C++20 GitHub repo delivers from-scratch implementations of low-level system components like LRU, LFU, and ARC caches, with plans for red-black trees, memory pools, and garbage collectors. Header-only and zero deps, it lets you drop in thread-safe caches with O(1) puts and gets via a simple API: create a cache with capacity, put keys/values, and fetch with optional returns. Perfect for devs exploring beginning C++20 GitHub projects or needing lightweight C++20 features without bloat.

Why is it gaining traction?

Stands out with pure C++20 from-scratch builds—no external libs, just stdlib—making it dead simple to integrate into any C++20 project. Thread-safe caches handle real-world concurrency out of the box, and the K-LFU variant fights cache aging better than basic LRU. Devs dig it for cpp from scratch learning, showcasing C++20 GitHub tricks like modules in a zero-deps package.

Who should use this?

Systems programmers building embedded tools or high-perf servers who want dep-free caches. C++20 enthusiasts studying from-scratch implementations of LRU/LFU/ARC or red-black trees. Students hunting C++20 PDF GitHub resources for hands-on low-level data structures.

Verdict

Grab it if you're prototyping C++20 caches or learning internals—solid tests pass cleanly, header-only shines. But at 42 stars and 1.0% credibility, it's early; stick to caches until roadmap fills out.
