Advantages of flat_set
- Since the elements are stored contiguously in memory, it can be faster than set for operations like iteration and finding elements.
- It has a smaller memory footprint than set, which can be advantageous in memory-constrained environments.
- It is a more cache-friendly data structure than set, which can lead to faster access times for frequently accessed elements.
C++ 23 – Header
<flat_set> is a header file that provides the implementation of the std::flat_set container class in C++, which is a sorted associative container that stores unique elements and allows for fast access, insertion, and removal of elements.
The flat_set is a container similar to the set but its elements are stored contiguously in memory. This can provide faster iteration times and better cache locality compared to std::set, especially when the container is relatively small or its elements are trivially copy-able.
