This happens to use C++20 coroutines because I'm lazy. It can
equivalently be written without.
I reworded measure.sh to use cmake instead of zig build. Again, I'm lazy
and don't wish to learn zig build today.
The flake had dependency issues
- for one, the beast archive references in cpp/build.zig.zon is gone;
- secondly the upstream zig flake does not have zig 12.0 ¯\_(ツ)_/¯
Luckily that's in Nixpkgs, so I switched to nixpkgs-unstable.
- I also added a `liburing` dependency to the devShell. This was to
test with uring, but it didn't produce better results
AuthEndpoint callbacks now provide pointers to the original
SimpleEndpoint structs, so their fieldParentPtr calls work.
Added extensive debug() logging to BasicAuth with .UserPassword.
