Rust Ownership and Borrowing

[@sumechans]

Not sure why I bought all these tutorials from Udemy, Packt etc, when this amazing tutorial was there free for everyone. Kudos to Doug. You are an amazing instructor.

[@dougmilford7814]

Thanks! Just wish you could have saved a few bucks. Oh well.

[@sumechans]

@@dougmilford7814 You mentioned on this video, tutorials on arrays, vectors and collections are coming, are they out?

[@dougmilford7814]

@@sumechans Sorry... haven't gotten to it yet. Life gets in the way sometimes.

[@sumechans]

@@dougmilford7814 Definitely worth waiting. Thanks!

@@dougmilford7814 Timing: sometimes, when we want to start something, the great product for free is not there yet and we have no idea that this great product would come a couple of weeks later. Since we do not have the patience, we pay for courses. And yes: awesome tutorial and great job. Thanks to you, I now understand why we use references and not the objects themselves.

[@parthokr]

This man has mastered the art of teaching for sure. Memory management has never been this easier.

[@chucknorris7995]

I finally understand this concept! thank you so much!!!!

[@TheZazatv]

This is by far the best tutorial on that topic out there. I love that you've included every use case!

[@yanchaoli551]

best rust tutorial ever, looking forward more stuff coming

[@dougmilford7814]

Wow, quite the compliment! I'm finishing up Rust 3D Graphics in the Browser right now. Hopefully by the end of the year it'll be out. I needed a break from the bread-and-butter topics to do something a little more fun. After that I'll circle back to some important fundamental topics like concurrency and creating macros. So, yes, more stuff is coming!

[@anubhav200]

exactly

[@hamzamohd.zubair1709]

You have mastered Rust as well as the art of teaching

[@amans6504]

oh my god, never seen this much clear explanation of programming in general. Wonderful

[@kennethmarete5329]

This is the finest tutorial I have ever seen. It's well explained and illustrated with clear examples. Thank you Milford

[@estupefatos]

He teached me Rust and also how to teach. Thank you, Mr. Milford. You're a legend.

[@nathanielwoodbury2692]

Holy crap it has never felt so simple. This dude is a teaching master haha

[@nikoicardo9474]

Doug this is a great video. I like your sense of humor.

[@waynelee7320]

I'm a JS programmer. I found this idea of ownership and borrowing is exactly what I need in JS. Copies and Refs are so messed up in JS. It is the best explanation on this topic I've seen and cleaned up a hell lot of mess for me to understand Rust. Thanks!

[@freedoompictures6839]

Concise, to the point, fun to follow and really explains the thing in whole, not bits and parts of it. Your teaching speed is calibrated ideally which makes following the course easy. Finally found a channel to follow learning Rust. Thank you!

[@RenaudDenis]

Great tutorial. That is easily the most troubling programming stuff I've learned in years but I think it's growing on me.

[@dim-2d]

This is by far the best Rust tutorial series I’ve ever watched! Excellent work!

[@danvilela]

I am amazed with how can they build this kind of compiler

[@yuong8139]

All these tutorials in rust are amazing. Your teaching is exceptionally engaging, clear and organized. You are an amazing and wonderful teacher . Thank you very much for teaching. Much appreciated.

[@OP-hw4xj]

"If you cannot explain it simply enough, you do not understand it well enough", you sir most definitely understand the subject to the minute details! hats off to you for the amazing explanation!

[@niravprajapati1267]

Mind blowing 🤯! Thank you for video.

[@marcelijankowski9593]

In my new job Im being transfered to a Rust project, this video was really helpful, thanks!

[@sgwong513]

so far this is the best and crystal clear explanation for rust ownership and borrowing video that I had watched. appreciate for the hard work.

[@lukash7660]

Wow! Lucky to run onto your tutorial, it makes a lot of sense compared to other Rust tutorials, great job! As a python/js developer with some knowledge of c/cpp I find that Rust combines both worlds in a unique way which somehow makes more sense than traditional concepts.

[@maximodakila2873]

Where before I was hesitant to learn Rust because of it's high learning curve, now I am emboldened to learn it because you explain it so clearly. Thank you. Glad I stumbled upon your channel.

[@abraham7966]

Very fine and well created material. Concise, straight to the point, and easy to understand. Well done, sir. Well done.

[@adehenry9591]

Best tutorials on rust ownership and borrowing i've seen so far....the humor made it easier too 😊

[@hamol3d]

One of the best Rust tutorial series I have come across. Thanks for sharing!!

[@stphane]

Thank you for such a clear and exhaustive overview on Ownership and Borrowing concepts. Such free contents have no price and there should be as much "thank you" comments as there are thumbs-up on this video.

[@auniquehandle]

thank u ser, this is the best video on rust ownership and borrowing on the entire youtube

[@WouterStudioHD]

Rust is brilliant. I have quite some experience with C++ and I can totally see that Rust is just so much better. It's so explicit, consistent and well defined, while still being just as fast if not faster. I don't even know if I can bring up the motivation to write one more line of C++... Thank you for this clear explanation.

[@dougmilford7814]

Couldn't agree more!

[@-taz-]

Some languages are bringing back functional ideas that are older than computer science, even. Some try to clean up C++ like D and Go, or clean up Java like Kotlin. They usually remove or minimize inheritance, and maximize immutability. But Rust is the only one trying fundamentally new ideas. I've used C++ for 27 years, and I'm having a hard time with lifetime management in Rust -- the notations. Pattern matching is what lured me in, because I tried for years to do that well in C++, and I did alright, but then try getting some random C++ coworkers interested in algebraic types and overload sets. Good luck! I gave up. C++23 will probably get pattern matching, but lifetimes? Nope. Plus std::optional, std::any, and std::variant are a hodgepodge, and std::expected is still just a proposal.

[@drippedoutlawyer8166]

I finally get how it works thanks to you!

[@JDalmasca]

Love the enthusiasm you bring to these videos! It's really reassuring to hear you explain things as a newcomer might experience it: "What the ding-dong is that??" -- me, in the future (probably)

[@amidfallen]

wow! After watchin this video, the stuff with ownership and borrowing seems pretty straightforward. Thanks!

[@seanlacey]

Been working my way through the Book and have struggled with the ideas of ownership and borrowing. This video has really helped my understanding so thank you! I will definitely have to check out your others

[@bobgodwinx]

Thanks very much it really helped me understand the craziness behind the hood of borrowing and ownership!

[@rahulek914]

Very good coverage of seemingly difficult concepts. Your efforts are experienced through easy to understand samples. I suggest the topic of covering the standard library as much as you can. Thanks.

[@dougmilford7814]

Thanks :) I appreciate the feedback. I'm currently polishing up a mini-series on doing 3D Graphics in the browser with Rust, and it should be out in the next few days. I needed to tackle something fun, but I'll be able to get back to the bread-and-butter topics (including the standard library) by next week. There's so many topics I want to cover, and only so much time. It's motivating to get messages like yours, though.

[@fbytgeek]

Subscribed after watching just one video!! Content is of quality! Thanks a lot for your efforts! Please continue creating more content as time and circumstances permit.

[@ClabirdDoudou]

Thank you very much ! The quality of all your Rust tutorials is amazing.

[@TrevorSullivan]

This is an amazing video! Thanks for helping me understand memory management in Rust better. I'm working on my own video series on Rust, that's currently available on my channel, but I haven't covered borrowing and memory management yet. Keep up the great work, Doug!

[@dkarlovi]

Excellent explanation, it finally made it click for me! Thank you very much!

[@williamb.2031]

Awesome tutorial as always! Love how your commentary has a perfect mix of technical with a hint of goofy. Always makes them fun to watch. You briefly touched on functional programming, seeing some functional programming related tutorials in Rust would be fantastic :)

[@dougmilford7814]

This is the second request I've had regarding functional programming I had in a week. I'll go ahead and move it up the list. Thanks for watching!

[@cerex1273]

I got the concept reading the official rust book but your clean explanation with examples is true gold. I'm sure you spent much time creating this tutorial with passion so you deserve all my gratitude for your hard work. Thanks so much :)

[@dougmilford7814]

Ah, thank you! Yeah, these videos are much more work intensive than they appear. This topic I spent quite some time trying to figure out how to describe it to others without confusing them more. I'm just so glad it seemed to come out well and the viewers are finding it so useful :)

[@ehsankhorasani_]

These tutorials are like a GEM. Thank you very much

[@keeganspeck]

I don't often comment on videos, but I've watched about a dozen today on the concept of ownership/borrowing/references in Rust and yours was *by far* (and I really mean *by far*) the clearest and most effective lesson I've seen on the topic. Kudos and thanks. Seriously.

[@LinuxForLife]

The best video I have ever seen about this topic! Thank you.

[@dougmilford7814]

Hey, thanks!... you're very welcome :)

[@KiffinGish]

This has to be the best explanation of ownership that I've ever seen ... it now is all suddenly making a lot of sense!

[@dougmilford7814]

Hey, great! Yeah, tricky topic. Took me some time to wrap my head around it, too. I think it takes everyone a bit of time. Glad it's starting to click for ya :)

[@KiffinGish]

@@dougmilford7814 Your approach by handling the heap and stack separately is what helped me get a better grip on this tricky subject.

[@_myron]

Great tutorial Doug, can't wait for the parallel programming guide!

[@sudhir1274]

The explanation of ownership and borrowing is very well explained in this tutorial. A lot of misunderstandings and misconceptions in Rust have been cleared up by viewing this tutorial. This concept is not very well explained in any other literature or tutorial. I really appreciate this whole series. One of the best tutorials on Rust in my humble opinion. I have viewed others and none are as clear and concise as this one. Thank you once again.

[@dougmilford7814]

I truly appreciate all of the positive feedback! I don't make any money from these videos, so having others enjoy and learn from them makes me happy that I could help others learn Rust. It makes my day when I get feedback like this :)

[@zoidian601]

Ownership... what the ding dong is that?! But for real, great presentation. This was really clearly explained. Glad I found this channel

[@mattforrest9010]

Thank you so much for your Rust tutorials. They have been extremely valuable and definitely the best I've found.

[@sylver76]

Thanks! This clears thing up a lot.

[@andermetalbrasil]

Your videos are very well explained. I'm just a beginner hobbyist programmer trying to learn the Rust language, and your videos surely are a great help. My only experience with programming is a little of GDScript, the scripting language used in Godot game engine. I'm studying Rust for about only two weeks, reading the The Rust Language Book from the official website and watching some videos about the language, and I think I'm starting to understand how borrowing and ownership works, but I'll have to practice it a lot to make it natural to me. When I think I'm ready I'll try to make a game in Rust. Thanks for your work teaching this amazing language.

really amazing ! kind of myth busting on Rust ! Thanks Doug !

[@peperudpeperudski1911]

Best explanation I’ve heard. Can’t say I care much for the web assembly gymnastics at the moment, but I really hope to hear your take on threading, async io and other features that make a language “complete”.

[@philipjin7572]

Thanks Doug , a very good video to explain rust key function!

[@mageprometheus]

Perfect clarity of concept. Thank you.

[@indrajitbanerjee4350]

Wow rust's memory management is kind of revolutionary. It feels almost unbelievable that we came this far in programming languages and took us this long to figure out the fact that it is indeed possible to define rules of a language that doesn't permit most memory issues in the first place without a runtime garbage collection. Kind of makes the subject of garbage collector moot doesn't it? C++ does a good job despite being backward compatible with C. The only issue is C++'s solutions are library features mostly and can't come close to the rust's features that have much deeper ties with the language and the compiler

[@dougmilford7814]

Yeah, Rust really re-thought the rules and came up with something groundbreaking. That took real courage.

[@nickssmirkingrevenge]

Great job! You explain everything so clearly and in a really engaging manner. Thank you!

[@dougmilford7814]

Glad you enjoyed it!

[@KontaJapan]

I finally understand ownership and borrowing, thank you!

[@idiot7leon]

Thanks! Very clear explanation, and fun lecturing! I enjoy it very much~

[@Barskest]

You mention in the video that functional programming is the way to go. I've been trying to find information about it with moderate amounts of luck, could you possibly make an introductory video explainign some of the concepts with simple examples as you do with the topic of ownership in this video? :)

[@irlshrek]

so good! cant wait to watch more of your Rust content!

[@igorkuchin9302]

Thank you very much! This makes ownership and borrowing quite clear.

So quality content! I thought this was a talk in conference!

[@harrypotil860]

This is amazing content. But 30:41 why Rust will think so ? Struct can have thousand fields ..! Compiler will check the struct too right?? Can anybody explain?

[@harrypotil860]

I got to know that it’s nothing to do with thousands of fields. By default struct doesn’t implement copy and that’s it. You should either implement COPY or reference.

[@h1k0usen13]

These videos seriously deserve more views

[@dougmilford7814]
