It saved me 20ms, and given your using C, saved you dealing with uthash or similar, so probably worth it.

The hashmap is probably a more generic solution though

[–] [email protected] 2 points 5 days ago

Certainly more generic and less prone to user error too. Indeed dealing with hash maps or any advanced data structure is a pain with C, this is where generics or templates really shine, especially if you have control over lifetime aspects as you do with C++ or Rust (e.g. moves, lvalue references, constness, etc).
