LOVE RUST! Been doing my senior project for my CS degree in Rust to help me really learn it. Been an absolute blast!

I would like to say that Rust is unlike other languages where you can learn as you go/while experimenting. I'd really recommend reading through the resources people mentioned before jumping in (steep learning curve).

Upper case separated but underscores is called "SCREAMING_SNAKE_CASE"

Rust has a great documentation that is even available offline when you install it, and in the documentation there is the rust book which explains all its concepts with practical examples. I think it's a must to go through it because it's quite different than typical languages I think (although I only really know C and python).

Video on utf-8 would be nice!

Thank you so much, I was just wondering about this language and wasn't quite sure where to begin. Hats off to you Gary

Great Timing! I've been thinking for a while to learn Rust (I already know C and a little C++). The video was very clear, fast and efficient. Loved it. Will be eagerly waiting for next lecture Professor!

Great introduction to Rust. I am looking forward to the next instalment in this series. I would also be interested in your presentation of UTF-8.

I'm so glad to see you cover this

Quickest, most consise Rust introduction I've see yet. Kudos!

I like it. Thanks for the intro. Something to do while in lock down. Learn a new language.

I really like your explanation of String vs str. Not a complete definition but I think very good when you're hearing "rust has 2 string types" for the first time.

Great intro video. I'm going to be using rust at work in the next few weeks and this is helping me to get a basic understanding. I was educated in C++ and so far, they are very similar!

Thank you for our Lesson Uncle Gary. It was very clear and informative.

You're showing some fantastic breadth on this vid, Gary. I'm, foremost, a programming nerd and I've been following you for your hardware coverage and have been delighted with it for its accessibility. But I, myself, with a degree in computer science, am just beginning with Rust and I love it. They've run with the C++ community's long refined practice of RIAA memory semantics and have turned an art to a science with their fundamental build of a programming language atop it. It's amazing. The Rust-lang book is my homepage as I plod through it all. The borrowing tricks are very clever and to be completely honest, I wish there was a garbage collected version of the language so as to relax the learning curve so that the final jump to rust could be just laser focused on the borrowing and ownership stuff. It is real crazy and cool. I like garbage collection less and less as I reason through how graph algorithms absolutely destroy the CPU cache with frequent invalidations. And the CPU cache isn't just a nice-to-have on the side. Good performance can't be had without it.

This is a great introduction to the Rust language. Gary really does explain and in a clear concise manner.

Wow, Gary. You did sooo much work here. 👏🏽👏🏽👏🏽

At 14:07 I guess you wanted to say that constants are always imutable (instead of mutable).

This is a great style of video! I'm curiously prodding around the outsides of Rust to see what it's like and this is a terrific introduction to core concepts and features without being overly verbose or lengthy

Brilliant way of explaining things! Well Done!

Excellent and elegant introduction to rustlang. Thank you for the video !

I would pay for a full course on rust explained by you, This is really very clear and straightforward.

Thanks for the video I started rust this year and I found it fascinating

Hey Gary, I'm late to the party but I want to dive into rust programming and this video gave me an excellent introduction. Thanks a lot!!

Nice overview! I would really love a video on how to make code more... Rusty. I often still feel like I'm writing very iterative code, and would love some "instead of X, try using a more idiomatic pattern like Y" examples. Also something along the lines of "How not to panic!() when you see angled brackets". Memory safety and borrowing can be confusing for a bit -- But I found that the real brainteasers start when you encounter generics, traits, boundaries and macros -- and that's usually pretty quickly because Iterators, From/Into conversion and Result/Optional are so prevalent in other people's crates.

Very clearly explained, you've got another subscriber!

Thank you professor

Thanks Gary. You convinced me to learn Rust in this nice video

I know its not the niche of your channel, but can we please get a full Rust course 🙏🙏 This explanation was fantastic! The little things you mentioned on the side were actually very helpful in clearing many misconceptions I would have assumed initially. Please give us all of Rust you know 🙏🙏

I am about a year into learning and using Rust, about as old as this video is. Now I can really appreciate why Rust has been the most loved language in SO surveys for 6 years running. On a management level, projects leaders like it because the compiler catches so many bugs, which means they can put more trust on every of their programmers (junior and senior) to produce reliable, bug-free code. On an individual level, programmers like it because of all the modern ergonomics Rust brings to the table - type inference, Python-like string templating, iterators, message channels, official build tool, world-class documentation, and so much more. And of course to tie it all together, the programs that come out is hella fast - nearly as performant as well-optimised C and Cpp, and leagues above interpreted languages such as Python. It's a language so good it only existed in people's dreams, right up until it actually happened.

Excellent video! I've just started learning Rust, and I learnt a lot from this video. One minor suggestion: I found myself needing to seek back-and-forth a bit from the resulting output back to the code that produced it. It would have been nice to have both on screen at once. I know there's limited space when using big fonts for videos, but you could crop out the run/debug/stable buttons along the top, and it would create enough space for a few lines of output at the bottom. This (needing to seek back-and-forth) is one of the things where article/books are often better than videos (much quicker to seek by just moving your eyeballs than fiddling with the seekbar), so this would help get closer to that efficiency. You could still hide the output before you're ready to show it, but just leave the code on screen too when showing the output. Having a different background color for code vs output would be nice too. Alternatively doing something like quokka where you show the output as a comment on the same line as the code means that the viewer doesn't need to try to mentally match things up.

Thank you. This helped a lot :)

Every minute of this video is valuable ... I have just started learning Rust this week; and I only know python (2 years experience)... and this video helped me a lot... please do more Rust programming stuff.

Interesting intro Thanks for sharing :-)

Very instructive, thanks !

Excellent video! Thanks!

Nice one. It would be nice if you do a video on Haskell too.

Fantastic video!

Thanks for this

Thanks man rust is quite easy and you explained it clearly

Gary, what a great intro. Thanks

Looking forward to the second video, but I'll throw in a vote for UTF8 as well!

Good work. Thanks.

looking forward to seeing the sequel to this on memory, ownership and borrowing

*BOOOOM* Let makes so much more sense !

UTF8 lesson? Yes, please!

damn this is so good i was having hard time gettin rust ur video is gem.

excellent! Thanks

I was wondering about cloud computing. Like run my java app in cloud foundry, in aws cloud, azure, ali cloud. How much effort is running a complex rust app in different cloud environments, using the same code base.

Thanks -- revisiting after seeing the Google "go" language vid to compare the differences (many).

Best intro to rust

Thanks👍

@8:07 i tried to replace those with strings and i noticed rust cares about what type of quotes i use, which is kinda wild. cause what if i need to make a template string on the web? i suppose i'll have to store it in those "" quotes as a string. looked more into it, its like bash where you can escape characters you need inside a string so thats good

I have been programming in rust since 2 years ago and I wasn't aware about the named variables in the println macro 😂.

I'm just thinking of the hundreds of hours of my life I could have back if my work had been done in Rust instead of C++... I try to do as much as I can in C, but sometimes I just have no choice.

Nice video bro!

Awesome video, please do a video on UTF-8, I am subscribing to this channel for that reason only. Thanks again :)

You should make a video on Go

As a programmer that knows more than 10 programming languages including Rust, C and C++, i think Rust is pretty exagerated. You know, when i was learning C, i thought to myself: why does this language not have classes or at least libraries for the basic things like hash tables, or even maybe a way to check for memory violation at compile time. Then i read the libc (c standard libraries) and indeed C has many libraries, just that they are not classified as standard. This really troubled me, but with time, i realized why C is so, why a C compiler exists almost every hardware out there. C knows its place and it is as a mediator between hardware and human, a nice assembler. C11 included generics, but barely anyone uses them, it even added the bound checking option for developper, which people criticised. This leads to my complain about your points at 0:43: C and C++ are very popular and a lot of people use these languages without actually knowing what they are doing. Funny is the fact that the Rust community is filled with good C and C++ developpers. An example is what i keep seeing in C++: People using C style programming in C++ and calling themselves C++ devs. Instead of creating a raw array of raw pointers, rather use C++ std::array or std::vector coupled with std::unique_ptr.

Interesting stuff, but I'd like some more information on what is going on under the hood. For example, when you say let (w, x, y, z) = tup, are w, x, y and z references to tup values that become invalidated if tup is deallocated, or are they copies? I'm guessing in a memory-safe-to-point-of-madness language like Rust, they are copies, so the operation is more expensive than just referencing tup.0, tup.1, etc. Also, yes, do that UTF-8 video. :D

How fast it is ? Any benchmarking test ?

Seems interesting language and quite powerful, how far it has been adapted ?

hmm .. at 24:05 inside y block x is muted does mut needed as it comes under shadowing ?

Hello and thank you for the tut it’s really helpful fr, but am a beginner and I wanna learn rust how’s that possible?

UTF-8 DO VIDEO PLEASE

For the function `is_odd` at 28:17, the logic holds in a single line: (x & 1) != 0.

Start with something the learner is already familiar with, for example, a simplified order entry system, or a simplified person book inventory system, or a car maintenence scheduler system. A competent teacher can start at any point to accommodate the experiences that the learner brings to the table.

Trank you!

Is tulle the equivalent of JavaScript object? Why does rust not use curly brackets instead of paren?

a little guide on UTF-8 would be nice :)

what I also love in Rust is, that Microcontrollers are first class citizens. The Whole Rust Ecosystem supports Cortex-M out of the box

Sólo le veo dos cosas interesantes: las tuplas (que no dejan de ser estructuras) y que los tipos de datos tienen definido el tamaño de bits. Para todo lo demás me gusta más C.

I guessed that it was an ancient video so I can explore the whole tutorial but this video is 0 day old :'(

*GARY!!!* *Good Morning Professor!* *Good Morning Fellow Classmates!* Stay Safe Out There Everyone!

Will there be followup to this?

Hey sir im 22 and i wana learn coding where should i start by which language and where can we get a good idea about the language on the net

This is a good video and well-explained, which I appreciate greatly. But Woooo! I'm old school. I started programming in APL, Z-80 and 8080 assembly in 1978. I went on to design two programming languages myself: R-code and LIM. From my perspective, an immutable variable is a CONSTANT. It's RIDICULOUS to default all variables to constants. Additionally, The format for displaying a line of text is needlessly complicated and makes it harder to read and debug. For one thing, it shouldn't need a macro. Jeezy Joe! Trust me on this, as I have read and debugged code in several languages. Rust would have made me get up and walk out. Python is crazy too, with the rigorous white space, but it's not as crazy as Rust, and actually is pretty useful when coding for the Pi. Therefore there is nothing on planet earth that would induce me to code in Rust. Anyone who likes Rust, please reply and tell me why you do. Maybe I'm missing something. All good wishes.

Can I go straight into Rust or would it be better to learn something like C first?

Got news that Linux kernel would support Rust to some extent like for writing modules. Came straight up here out of curiosity to know Rust 😂

A variable thet's not mutable? Wouldn't that be a constant??

👍

hey Gary -have you ever worked in any software firm??

9:40 lol, that's amazing. Why would they allow shadow variables ? That seems like not a smart idea. Expressions seems really dumb, for example why not have return ? And then I realized, this forces the return to be at the end of the function. That was not as stupid as it seems at all ! Tip: with loop and while use a < > or instead of equal, so you know it will never end up in an endless loop in case you change some of the other code/calculations.

good video

It's a technicality, but Rust DOES have an intermediate language, it's just not usually what gets delivered and it's a part of the compiler. Rust is getting compiled to LLVM (low-level virtual machine) code, and other than the name suggests that is (in this instance at least, and AFAIK) used to compile further to Machine Code. The LLVM layer is what allows Rust to run on multiple platforms without requiring a runtime - like I. E. Java (and other languages with the typical 'intermediate language') or Python (and other interpreted languages) do. The only reason C(++) is able to run on so many platforms is because these platform holders or others put in a lot of work to make the compiler work, because in the end you need a language to Programm systems, and C(++) is what's used for these most of the time to this day. Rust doesn't have that luxory, but by using LLVM they can just port the LLVM Instruction Set and they're good to go. LLVM is also used by the C Compiler Clang and there's other languages that can be compiled to machine code using it btw. Coming back to Rust, they (probably, not an expert) loose a bit performance by using LLVM, but Rust makes up for it with other features that reduce runtime overhead (lots of zero cost abstractions) and you win a lot of other really nice to have things like I. E. The type-managed memory safety etc that improve code quality as well as ease development. I haven't really used Rust yet for lack of a good project to do on it, but what I have heard is quite amazing and right down my lane. Maybe you will give me a good project for it, or I'll get back to the neural network book with code I read and try and port the essentials from Python to Rust. Eventually...

If another coder can re-declare your variable without throwing an error, what’s to prevent that accidentally happening? (Expecting the next coder to be careful doesn’t count.)

How Rust compare to go (golang) ?

Can you swishy-wishy? x, y = y, x (a, b, c) = (c, b, a)?

a Variable that is immutable then it is not a Variable, it is a constant!

I tought .len counted the length of the string not the number of bytes of a utf-8 encoding. :( Is there a method to count the actual string length? edit: 1. Found it. see my comment bellow. 2. I understand now why the default is bytes. String length could still be easier :/

@4:12. For years I thought it was pronounced as “tooples” not “tuh-ples” 😆

I've lost count over the years of the number of trendy niche languages that were going to replace C or even C++. Anyone remember D? Didn't think so. C and C++ will always remain the standard languages for embedded software. There may be a case for using Rust in place of C as raw pointers and arrays are tricky for programmers to handle. C++ avoids many of these pitfalls by providing deterministic destructors for cleanup (RAII), smart pointers, bounds checked vectors etc. Modern C++(11/../20) also provides move semantics to distinguish between copying and exchanging data, as well as a whole host of other modern language goodies such as type inference, lambda expressions, direct iteration over collections, initializer expressions, etc, etc. If you want to learn a better C, learn modern C++!

does it have a lot of libraries/imports .. so you get a bunch of stuff for free? I try to write as few lines of code as possible. i don't like to re-invent the wheel. i care more about pre-built libraries (that are available "for free"), versus language syntax. :)

But, oh, that NAME. “What should we call our new programming language? How about ‘Rust’? Sounds good. Let’s go to lunch.”

Where's that UTF8 video Gary? 😫

yo gary this is a rust crash course IMO

I'm starting to learn Rust, but I'm wondering if the memory flaws in MODERN C++ are vastly overstated. For most projects it's a non-issue. How is anyone going to do a memory exploit of some silly game I develop, for example? Most systems programming is done in C rather than C++ anyway, So how can anyone say that C++ is vulnerable when it's not used that much in systems programming? It seems that someone has said that C is unsafe, and then thrown the baby out with the bathwater.

PUBLISH THE NEXT VIDEO NOW

Maybe I'm just old school but a "variable" that is immutable is better known as a constant. I really don't understand the point of this language pattern in rust, it's ridiculous.
