The latest feature for #FormaK: a managed #KalmanFilter runtime!

I'd been stuck trying to simplify the complexity of managing a process and multiple sensor models since I introduced calibration (which added more complexity... not helping...). In the end I landed on a single tick function call with a dose of #SFINAE that handles sensors of any type and takes care of the rest under the hood.

As always, it comes in #Python and #Cpp

C++ Code with a call to a function named tick. The first argument is a time output_dt, then an argument control, followed by a vector of sensor readings. Each sensor reading is encapsulated into a function call wrap which is templated with the type of the reading called Simple. Text Code Snippet: mf.tick(options.output_dt, control, { mf.wrap<Simple>(options.reading_dt_base + 0.05, SimpleOptions{}), mf.wrap<Simple>(options.reading_dt_base + 0.06, SimpleOptions{}), mf.wrap<Simple>(options.reading_dt_base + 0.07, SimpleOptions{}), }); Full code available at https://github.com/buckbaskin/formak/pull/17/files

False! In some situation, using deduced return type will cause the compiler to instanciate the body of the function, and in my case it was happening a lot with concepts since I checked everything.

Suddently, I had a bunch of instanciated functions that shouldn't have, and try to called (purposefully) unimplemented functions. Those were causing compilation errors where it shouldn't
