Poc of generating _data.rs from ../_data folder

I'm still hesitated about this approach, even though you're creating stack variables you still have some String fields that points to the heap (and that's a lot). Not to mention only that you are creating many variables on the stack.

I'd rather fetch the needed data from the disk instead of having everything in memory.

A more suitable approach is to have something like Redis, we can have in memory data for specific period of time (I'm thinking about backenders here 😅)

true, although, it will be significantly faster, the toll on the memory will be significant.

I can see that as a valid use-case, when memory is limited, and speed is not the most important, and the storage system is fast enough.

I can't see the difference between this and the first solution, other than consuming a lot more memory 😄

so, there seem to be different approaches, with different caveats.

How about having multiple solutions then :), and hiding each behind a feature? eg: features = ["from-storage", "from-lazy-static", "no-data", "from-stack" ] ? (The pure "from-stack" will be very interesting to work on, as we won't even need serde)

Dude, now we're talking! 🚀
