Well, Perl is great for small scripts that works on large texts, that you process with regex. I still use Perl from time to time, for that kind of scripts. Also commandline, instead of awk/sed...
Well, when you write async code, you may suddenly find your self needing to implement AsynRead or something similar. Suddenly you have to use pin, and understand how async worksbunder the hood. So, while I agree that async is not something fancy, it will possibly throw you in some quite advanced territory. The part I'm not sure I agree with is skipping the error handling. But I see what the authors intention is, to keep hairy stuff out of the way while learning the basics.
Fixed it.... I come from a language culture were we like our negations :) Also, not native english speaker, so combine the two and you are in for a ride!
That will always be prune to race conditions, where you check if someting exists (then some other thread creates it) and then you try to create it. You should always try to create first, then if it fails due to it already existing, fetch it. That is a good general rule for anything from hashmaps to databases.
This seems to be nothing other than shameless self promotion. Mods?
It varies, depending on if I have submodules or not. I see no reason to have a folder with a single mod.rs.
I updated the title of this post, as per your suggestion
That is pretty much the same policy I have for forcing adds on me.
Having programmed in C, I got the ownership model quite fast. I just think of it as "is this function going to do an implicit free on return", if not then it should just borrow it. And for C, you already had to think of ownership, just that it was not enforced in any way in the language... if you messed up the ownership to either got a crash or leak.
And as someone pointed out in another forum, this was most likely a multi-choise question so it is impossible to know the true Linux percentage.

Ok, so we use different search engine so you didn't find this particular hit. But, do you really claim that learning material is an issue here. And about my attitude, yes, I was a bit cranky. In general, you can ask any stupid question, heck I ask stupid questions all the time and they will be answered kindly. The rust community knows that lifetimes and stuff like that is complicated.
However, I'm quite fed up with the attitude that it is someone elses obligation to spoon feed you with knowledge that exists right under the nose... and that is a very common attitude amongst the "For rust to succeed..." evangelists.
