I'd be interested to know what the benchmarks of the two rust solutions are when inlining is disabled so we can get an idea of the different performance characteristics of each function call even if it's not a very realistic scenario. The other question I have is which style should you use when writing a library? It's obviously not possible to benchmark all the software that will call your library but you still want to consider readability, performance as well as other factors such as common convention.
