If std::string construction was the goal then sure, but that's not what the original benchmark that I've written was about. The goal was to find the fastest way to format an integer with or without std::string construction: http:

The new benchmark is even less meaningful because 1. It now constructs unnecessary `std::string` penalizing `format_int`: value+=fmt::format_int(i).str().size(); 2. The input is consecutive numbers which makes branches well predicted which

The formatting part but unfortunately it's just a clickbait: https://news.ycombinator.com/item?id=23311726

Unfortunately performance claims appear to be bogus. 1. ospan, performance claims seem to be based on, doesn't do any bound checks, so you can easily get buffer overflow. 2. fast_io generates a whopping 50kB of static data just to form

FWIW {fmt} already supports formatting of containers, tuples and ranges as of version 5.0 ( https://github.com/fmtlib/fmt/releases/tag/5.0.0 ), for example: #include <fmt/ranges.h> std::v

A lot of work has been done since 2017: the proposal is at its 9th revision ( http://fmtlib.net/D0645R9.html ) and is prioritized (but not accepted yet) for C++20.

You don't have to use Doxygen with Sphinx although you can.

Sphinx ( http://www.sphinx-doc.org ) used by Python and some C++ projects like LLVM provides a modern high-quality alternative to Doxygen.
