It took me about a year to build all of this stuff in C++. So I imagine since I've had to learn rust, it will probably take me the same amount of time if I can save time with dependencies.

In my experience, once you know the problem really well, yes you're right.

If you are building a complex prototype from scratch, you'll usually spend more time fighting the Rust compiler than trying out alternate design decisions.

I do know the problem domain well. My second iteration in rust already almost has an order book implemented.

Writing code in rust however is very fun! (At least so far lol)

Better than C++? Have you experienced any problems in Rust that C++ instantly solved? Not because I'm pro/anti rust/C++ here, just curious.

Writing Rust is fun in the sense that solving a puzzle is fun.

Great when that's what you set out to do (rewrite it in Rust^TM) can get annoying otherwise (solving/researching a problem).

Don't know why so many downvotes, probably because I confused Unix with "GNU kernel".

Here's the source (Jan 29, 1992):

    If the GNU kernel had been ready last spring, I'd not have bothered to
    even start my project: the fact is that it wasn't and still isn't. Linux
    wins heavily on points of being available now.
