@@letsgetrusty I agree, love reading a chapter and following up with your videos, super helpful honestly, especially when trying to consume such complex knowledge.
now, 2 years later, your dream of 100000 subs almost came true....great job!!!!!!! I love your videos!! would be nice to now how many subs you had when you published this video :-)
I've been doing rust in non professional setup for a while and I watched advanced videos of LGR and learned a lot of stuff I didn't know about traits/smart pointers/error handling. I said "surely I won't learn anything from basic control flow video here" - and I learned that break from loop can actually return... So far, I keep finding gems in every video, no matter how basic.
Watching this and seeing you smile when you say "we can all dream" after setting Subscriber count to 100,000 and looking at your subscriber count sitting at 93.5k gets me so stoked for you! You'll be getting there in no time Bogdan! Keep up the amazing content, watching through this playlist has taught me so much. Thanks for teaching everything so clearly!! Cheers :D
This is awesome, I'm non-native-english person, so reading the book and having somebody explaining some things in voice is a really good support. Keep it up man! Great job!
Thank God the if statement only looks for boolean. In Ruby the if statement can be boolean, numeric, nil and I have seen crazy codes in the if statement where a function is used and the function can return any 3 variations of bool, numeric, or nil. It makes it extremely difficult to read the code and convoluted. I love how in Rust it is explicit boolean.
Keep popping out quality tuts and you'll reach 100,000 subscribers for sure! Thanks for the great tuts. One thing I was wondering tho, would it be possible to add chapter numbers the the vid titles?
3:07 Another difference between `let` variables and `const` "values is, that you cannot shadow constant variables/values (or am I wrong here?). That gives an additional security that you don't accidentally redefine its value.
@@letsgetrusty I want to add another note. Sometimes initialize the variable with `let mut new` and then later redefine it as `let changed = new`. - The name change has the benefit of making it clear in the document we are using a changed state of the initialized variable. Just a little bit more readable at times. - But most importantly the mutability changes. Now the best part of it: If the variable/struct or whatever object it is does not implement the copy trait, then no new space is allocated. The ownership is just transferred and the benefits like changing mutability comes for free.

i really appreciate you taking the book and converting it into video format, i have a hard time keeping focus when reading programming books and much better learned when i can "hear" & "see" something rather than "read" it. a bit ironic given programming is all about reading and writing code, but 🤷♂️
Well I don't know how to say it but thanks for existing and making this series I was looking for it I hope I'll see some real rust projects on channel too that'll be helpful
Really liking these videos, i hav ethe book but sometimes after coding all day at work i cant focus as much so just following along with the videos helps and once i start i get into it again. Thank you
Guys, I rarely read books and have web dev background, I think the rust programming book is pretty good. Definitely these videos are also a great resource.
I’m watching it just as a hobby as it’s being so easily perceived. I really enjoy the format, how compact and at the same time comprehensive the videos are! High five for the efforts ! … ps The hell with that, this is probably gonna be an unusual comment but I also enjoy your background !
Very nice video of nice playlist, bro you can think of this as your investment coz as rust finds more popularity you will surely get noticed. Cheers !!
Getting pretty close to 100k subscribers :D +1 to everyone's previous comments. It's been super easy to follow these tutorials along with reading the book.
a question: when looping through an array, what's the difference between `for el in a.iter()` and `for el in a`, because both works and in the Rust book (as of July 2022) it uses the `for el in a` version, without mentioning the `iter()` function
No one in the comment section talked about shadowing being bad. I work in legacy c code and the codebase is very big with thousands of line in a function. It makes me anxious about the number of bugs that shadowing of variables can create allowed in the same scope.
if you're reassigning an immutable variable and even changing its type through "shadowing", then how is it still immutable? I can see if you were doing shadowing inside of a function but we're able to redefine the top line declarations. Confused because it doesn't seem like strict typing and potentially not memory safe.
Weird to come from JS, I tend to think about tuples as a convention for arrays instead of a different kind of data type. Also arrays with variable length and fixed length arrays as different is also weird.
Hi I'm coming from python, It's kinda weird that at 12:00 you have to "return" or in your case "break counter" to return the counter assigned to a new variable "result" couldn't you just break, and println!("The result is {}", counter) Seems like overkill.
what extension are you using in vs code for rust using that you getting full details of the each datatypes and its features, just like for html css MDN reffrence is recommend when hovered would be helpfull if you tell me please
in shadowing, how we can use the first variable, for example - let x =5; let x =9; println!("x = {}", x); this is always print 9, but how we can use the first 'x' now??
I've watched so much of this series, and loved every minute. Then I heard you pronounce tuple, and it was so jarring and I instantly forgot everything I've watched. I'm sad that you're part of an enemy faction. I don't even want to know where you stand on tabs v spaces. I don't know if I could stand to hear the answer.
Why does "Let's Get Rusty" have to be typed, of all things, as &str. Literally useful for nothing. How many other string types does rust have now? Ridiculous. So many problems.

just when you set subscriber count to 100k and said we can all dream, looking at the actual count rn, your dream came through :)
I've just looked in the comments to see if someone's already commented this
People might criticize following the book, but it's really helpful to have this in video/audio format to reinforce the lessons
Agree, also Bohdan has very good implementation
So much more approachable than the book on its own. Def appreciate your content.

Very Useful Thank you
What a beautiful language!
Thanks to ur vid! I am getting rusty :)
It would be really nice if Rust had return type deduction i.e. “fn x() -> auto {…}”.
Great videos! Thanks a lot for this content!
constants might be also (probably?) stored in data segment of the process's memory (i dont know im guessing please correct me if im wrong)
Great vid!!!!

how to change the steps from 1 to a higher value in the for loops using range?

finally the sub_count matched the real sub!

I am getting error in rust 1.75.0 for the below line:

in shadowing, how we can use the first variable, for example - let x =5; let x =9; println!("x = {}", x); this is always print 9, but how we can use the first 'x' now??
hi husky
Practicing one video a day to get rusty.
LOL, that's the university district.
Is it just me or why is shadowing a thing?
because appearently naming variables quantity_string and quantity_number is le bad
You can actually just do the for loop without the iter
1:44 u want your subscriber count to be a constant ? U like to stagnate ? 😋
