22 characters is significantly less useful than 255 characters. I use this for resource name keys, asset file paths, and a few other scenarios. The max size is configurable, so I know that nothing I am going to store is ever going to require heap allocations (really bad to be doing every frame in a game engine).
I developed this specifically after benchmarking a simpler version and noticed a significant amount of time being spent in strlen(), and it had real benefits in my case.
Admittedly just storing a struct with a static buffer and separate size would have worked pretty much the same and eliminated the 255 char limitation, but it was fun to build.

You can still use more than 22 characters; it just switches to the heap.

I would put good money that using 256 bytes everywhere is going to be slower overall than just using the heap when you need more than 22 characters. 22 is quite a lot, especially for keys. ThisReallyLongKey is still only 17.
