I’ve only worked in software for about 15 years, so don’t have much experience outside of git.

But my first job used Microsoft Team Foundation, and I didn’t need any experience to know that user experience sucked. I’ve also done the “date named zip file” type of version control, which is not ideal.

When I started using git it just made sense to me, have had no major complaints since.

I solved it by using indicies instead, that way I got around the borrow checker.

I used a separate vector when I first solved it, but wanted to try out this solution as well.

Using indices worked, thank you!

OK, so I’m thinking…

The error says I can’t combine immutable and mutable in the same function. I guess this makes sense, and that it’s because I’m not allowed to mutate an object while accessing it.

Is this a correct understanding of the error, or is there anything I can do to use this approach?

Thanks, I tried that. But now I get the error.

cannot borrow cards as mutable because it is also borrowed as immutable

Thank you. I made the change suggested below to the linked one, but it still fails with the error.

cannot borrow cards as mutable because it is also borrowed as immutable

No, that’s probably wrong.

I’ve just been trying different combinations of borrowing, but I can’t get it to works.

I’m pretty sure it’s the cards[id].copies += add that is the cause of my issues.

Maybe I’m wrong, but using http could create a MITM vulnerability.

And for me this issue is my browser is setup to block http URLs. It’s just not a good look.

Hmmm, hosting a hacker post without an https url… 🤨
