CPP-CacheTools

Warning: still in active development! Use for production at your own risk. CPP-CacheTools is a header only library (C++17, older versions are untested) to simplify caching in CPP. It is built using the usual concept of zero cost abstraction. It's hightly customisable thanks to its modular design.

Using the cache

So far, there are two ways to use the caches provided by this library:

1. Wrap a function (similarly to Python's lru_cache)
2. Use the cache explicitly.

For the first case (see examples/function_wrap.cpp), it's as simple as:

std::size_t foo(std::size_t bar) {
    std::cout << "Received bar=" << bar << std::endl;
    return bar * 2;
}
//Create LRU cache of size 2
auto cached_foo = LRUCache::wrap(foo, 2);

int main() {
    cached_foo(1);
    cached_foo(1);
    return 0;
}

In this case, the library takes care of thread safety for you.

In the second case, you can access the cache through two simple methods, get and insert.
