I genuinely think this video should be included in The Rust Book. It is an absolutely incredible resource. Thank you Sreekanth!!! This is amazing.

This video was exactly what I needed to understand Rust's memory layout better! One thing that was specially helpful was the trait objects part. I had never understood at all what was happening behind the scenes with that, but now I have a better idea.

This is an excellent video! It really helps you understand the WHY's of different memory management techniques in Rust. Many Rust videos explain how to do things, but very few explain why to do things. This video is a must watch if you really want to understand Rust under the covers. Well done!

Thank you for uploading with better audio. I could not stand the voice of the other version, but this one is alright to listen to. Great video!

Thank you for your work. This video clarified many questions I had about memory alignment and helped me to understand how Rust is able to perform some optimizations, such as using a single usize for storing an Optional RC and Box. Keep up the good work!

This video should be part of "The Rust Book". This really explains why rust has so many data types. We need more rust videos. Thank You Sreekanth 👏👏

Thank you for your work, this is I think the best video I've seen about this subject and the first time I clearly understand the memory management in Rust. Clearly a video all people learning rust should watch. Really nice explanations on why things work like this and not just how. If you could do a video about async rust / Tokio that would be awesome !

This is the best rust explanation video in the world. I would give anything if there also is an in-depth look at the concepts of functional programming in rust explained like in this video because those concepts are crucial to understand rust and I'm still struggling to understand them.

This is cool. Can you tell us what you used for animating these graphics and the text? Also what audio generator is used here?

@sreekanthpr Жыл бұрын

- For this one, I used powerpoint to generate the video. For all other videos in this channel, I use github.com/ManimCommunity/manim. - Audio is generated with TTS service in Azure. Combined both with Davinci Resolve. - Subtitles with timings can be generated with github.com/m1guelpf/auto-subtitle (minor corrections will be needed).

Better yet, do you have a written version of this with embedded images of the diagrams in this video? -This is quite informative, but the generated voice's intonation is making it difficult to pay attention or process the information given.-

Personally I find this video extremely valuable @Sreekanth not just for Rust for compiled languages internals. Question I have what is the font used ? It looks like Jetbrains Mono but with some font ligatures turned on. Not sure what are the values

very good video! first time I really understood how stuff works behind the scenes! especially with rust enums - I didn't know it's like a union maybe do a follow up video on interior mutability, that'll be really interesting!

Excellent video. I just wish animation of the stack to show chunks of memory allocated like a stack (one on top of the other) and freed the same way. I find it more intuitive.

35:10 probably not true, because the same example not compiles, if use something meaningful like println, not drop upd. i mistaken, seems like thats because of using println

i don't understand why can't slices be allocated on the stack? in c++ they do and i think it's the same in rust also are sou sure that enums store index for each element? in c++ variants only the index of the alternative is stored which is enough to denote the type of the underlying union.

around 11:00 isn't it a move instead of copy?

@sdbg 2 ай бұрын

it’s a copy in memory level. Move is a compile level thing.

Actually, at 19:10 you've made an incorrect amend. Trait objects are in fact DSTs, that was correct. Remember you can't create an array or slice of trait objects - [dyn Trait] - or receive one as a parameter - fn func(x: dyn Trait) - or use `self` in a Trait method, because each Trait implementation will have a different size. What do have known sizes are owned trait objects - e.g. Box and other smart fat pointers - and references to trait objects - &dyn Trait.
