We can hide the direct array from external view and instead provide functions to retrieve the necessary info. This has the benefit of completely hiding the makeup of the SinkDetails structure from the rest of the code. Given that this makes the array hidden, we can also make the array constexpr by altering the members slightly. This gets rid of several static constructor calls related to std::vector and std::function. Now we don't have heap allocations here that need to occur before the program can even enter main(). It also has the benefit of saving a little bit of heap space, but this doesn't matter too much, since the savings in that regard are pretty tiny.
