Absolutely loving these videos, watching these make so much more sense then everything else I've seen

[@parttimelarry]

Thanks, looking to pick up some Rust, glad there is a channel focusing on this. Subscribed!

[@minastaros]

I agree, what the user actually want is not "loop over something, see if it fits, and then stuff it manually into something else" but "just gimme only those that match, and bundle them up, by the way".

[@zainjadoon759]

btw when you finish the book, you should make tutorials of ggez the game library because it uses a lot of stuff that you learn in the rust book and it is relatively easy. You could make tutorials on how to make flappy bird or other games for example.

[@nyzss]

i'm still watching the videos and learning more about rust and i've been thinking of doing something with ggez, bevy or amethyst (thinking more about going bevy as i've heard that it's more straightforward, but i'm still not exactly sure, some other opinion are welcome), and would love to see some kind of tutorial in any of these or other libraries.

[@letsgetrusty]

Will definitely do game dev at some point!

[@zainjadoon759]

@@nyzss I have heard that ggez was really easy and straightforward and I am pretty sure it can work with wasm with ggez wasm.

[@nyzss]

@@zainjadoon759 thanks for the advice, yea also heard that ggez was quite easy so i'll give it a try first, and also thanks @Let's Get Rusty for these videos!

[@exoticcoder5365]

Yo I catch up all the episode now, Thanks so much so much 🙏🏻

[@SilvestreVivo]

These videos are gold, thank so much for your effort and content. These explanations are much better that what I read in the book.

Iter probably has better performance in general because the data locality is always better. This is more true for massive iteration. Very similar to the new pipe operator in c++

Keep up the good work!

If I had a dollar for every time I've seen an exponential time solution unknowingly implemented via iterators+adaptors - Use them like spice. Invididually, they may be zero cost, but this does not mean algorithms don't matter! They do! In the wrong combination they can indeed produce absolute horror shows of extremely slow code. Iterators or not, always be cognizant of what you are writing.

[@SJ23982398]

Can you give an example? Or a link to examples?

[@redcrafterlppa303]

Can you please make a video about making iterators for collections and the different types of iterators?

[@inx1819]

yess

[@GolangDojo]

Please make a tutorial on how to get that sexy voice

[@thoyo]

May I ask, what do you use Rust for in your everyday life? Is it primarily used for your job?

[@letsgetrusty]

I have a full-time job that doesn't involve coding in Rust unfortunately. I am learning Rust in my free-time.

[@thoyo]

@@letsgetrusty Gotcha, thanks for replying. I only ask because I don't see a lot of jobs for Rust. I'm mainly learning it to code Solana smart contracts.

[@jacobhinchliffe6659]

@@thoyo is solana fun to develop for because I'd like to make a token maybe lol and I have nothing to make in rust atm

[@thoyo]

@@jacobhinchliffe6659 that's really cool! I hope you keep us updated on your progress

[@hymppex]

@@thoyomy guy you still alive ?? (Am learning it for solana as well, if you’d be my mentor i would be very grateful)

[@JuanDeSouza7]

holy s*** you have office, bedroom and kitchen all in the same room?

[@SatumangoTheGreat]

Might be a digitally inserted backdrop. I think his kitchen looks exceptionally tidy every time. Unlike mine :-)

[@unperrier5998]

If your iterator is in the critical path then you'll feel the cost of the so called "zero cost high level abstraction" as you like to name them. You're telling the viewer there's virtually not cost when there's one and in most cases that's probably fine but in some places where performance matters (remember, Rust touts being as performant as C, if not more performant!!!) then those abstractions will waste cycles calling functions like next().
