Rust Tutorial #9 - Memory Management, Heap & Stack

Hi everybody, and welcome to video number nine in this Rust Programming tutorial series. In this video I will cover a general introduction to Rust memory management. This video will serve as a knowledge base on this topic, allowing you to understand more complex topics in memory management. Primarily, I'll explain the memory stack into the heap. Enjoy!

Will this series be continued? I'd love to see more of these, great videos!

Still waiting on Rust Tutorial #10 - Ownership

[clot]

Please continue the series Tim, I love rust and it is a huge language. I hope you cover mos of the things in it

[unstablecoding]

Tim please continue this series, PLEASE?!!

10:50 - string literal like "true" is actually stored in the read-only data segment of the executable. In the stack, value of 'a' is a fat pointer (pointer + length) to this read-only data segment.

Hey Tim, I can't say my thanks enough for you. You are the person that inspires me to start my coding channel. Because of your channel, I was able to jumpstart my coding experience and learn more on my own. If anyone is reading this comment and is starting out on their coding journey, I highly recommend Tim and Sentdex for their amazing projects. It's because of people like Tim that motivates me to learn other languages besides Java, which is being taught in my school (and very poorly taught). Anyway, Tim, keep up the amazing work and I can't wait to see how far you'll go with this Rust tutorial! ❤️

[MarioPL]

So, yeah, I'm addicted to this series now. Need more.

Thank you Tim for these videos!
This was a great introduction to the rust syntax and I hope that you continue the series.

[davidsimek]

Thanks, I am beginner to medium Java developer and i wanted to learn something more low level. I am happy i found you. I cant hold and I am learning other things because I cant wait for another video, but these fundamentals are super interesting and i wouldnt probably learn them in this stage by my own study. Again, thank you for this.

[alfredomenezes]

This rust series is amazing, thank you very much, can't wait for the next episodes! I've just turned a member of the channel to support you with that ❤️

[akiratoriyama]

Tim of you read this comment, please continue this series at some point. It's the most comprehensive rust tutorial in YT.

[mechwarrior]

Amazing series! I love that it was aimed at the intermediate programmer. I hope you will continue this!

[minebuddies]

Pls continue this seires, you are a very good teacher!

Also the heap isn’t that much slower after you have obtained the pointer to the starting memory page.

You still need to dereference an address but the same goes for the stack pointer that you need to count back from the current point to the right variable that’s actually an extra indirect addressing function whereas the heap it’s optimized so that the pointer is already in a register “load effect address” and the data is also obtained using indirect addressing with offset. So in use it’s pretty similar in speed on some systems even identical because they don’t have shorter opcodes for best by addresses.
But yeah, the allocation and freeing is where the performance pain is. And in some cases also the fact that the data is too large or randomly accessed to fit in level 2 cache.

[CallousCoder]

You forgot that before a and b there’s the return pointer from where example() was called. And ofcourse there’d no name associated in the stack, the arguments are derived from their size.

And the values aren’t removed from the stack, the stack frame pointer is subtracted. The stack is never cleared that’s why it’s so fast, it’s just a stack pointer register that’s subtracted from.

Tim, have you given up on this playlist? I know you've got a lot of irons in the fire, but you did the first nine of these in one month and now it's been over two months since the last.

[ktlknss]

Tim, continue this series, you explain Ⓡust so well!

[uarweak]

Please continue this series. Your videos are a 10/10

[LacksonMunthali]

Hey Tim,
Thanks for these videos.
May you kindly continue the series.

[scottb]

The programming language FORTH is a great exercise/example when talking about the stack.
