Visualizing memory layout of Rust's data types
Переглядів 28 тис.Рік тому
Covers how a binary is executed, what segments are mapped to memory, the purpose/working of stack and heap memory, and how values of Rust's data types are laid out in memory. The data types that we cover here are integers, char, Vector, slice, String, string slice, structs, enums, smart pointers like Box, Rc, Arc, Trait object and Fn traits like FnOnce, FnMut and Fn. We also cover the differenc...

Inspecting the map header in Golang
Переглядів 1 тис.Рік тому
When you create a map variable, the variable stores a pointer to a map header struct. The fields of this struct can not be accessed in normal Go programs. This video will cover the procedure to inspect fields of this map header struct. Details regarding internals of map data type in Golang was covered in: ua-cam.com/video/ACQs6mdylxo/v-deo.html

Holy fuck finally
sbrk is not a syscall
Hello, Please create mode videos like this please!!!!
HELLO, CAN YOU MAKE MORE VIDEOS ON PYTHON PLEASE?? WE ARE EAGERLY WAITING
Wow
So every variable is heap allocated... sounds like a cache locality nightmare
This is the best video explaining variable scope of Python.
Very cool🎉
but , what's going on, what's your next video about rust ?
how is this gonna fix my divorce
An amazing video....
What a genius this man is...Where did you learn so much thing?
I heard the word 'function' too many times and now I've forgotten what it means.
Super useful information every python programmer need to see this you are great man and you rocked it🎉🎉
I'm really impressed, what a great content avaliable for FREE! Please keep up uploading videos.
so great👌
Wonderful work!! Just Wondering how did you make thes code animations? Which Tool did you use?
Please do this extended explanation also for containers such as deque hashmap btreemap etc. Thank you for effort put in this video.
I can recommend Jon Gjengset's Crust of Rust about collections for that. It's available here on UA-cam
Great explanation.
This was great
Thank you so much
This is among the most insightful videos on UA-cam. Well illustrated. I'm working on a quiz from the transcript of this video.
Bill Keys
thanks for class, can you share used Presentation?
@5:25 When the PyVarObject gets its refcnt inremented to 2, should the objects contained in the list also have their refcnt incremented?
I guess it's sufficient to not increment their refcnts. In that case, all CPython needs to do is ensure that when the PyVarObject refcnt becomes 0, it decrements the refcnt of the contained objects
much help video, thanks guys
around 11:00 isn't it a move instead of copy?
it’s a copy in memory level. Move is a compile level thing.
this feels like i now know something that I'm not supposed to know
what the actual fuck
AI uncanny valley voices are bad and you should feel bad.
Awesome

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 👏👏
Hey! Great video! I’d love to do a voiceover for this to make it easier to listen to.
How to contact you bro? I have 2 question in Python. If you can able to answer.
Is this presentation available anywhere?
Fantastic. Especially showing the implementations through programming languages.
Amazing content, please do more rust themed deep dives
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
I use github.com/be5invis/Iosevka
这个视频实在讲的太好了，解答了我好多关于Rust的疑惑以及Java中的一些疑惑!!追过来点赞
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.
i love this video so much do you have sources for this material?
this video was such a pleasure, <3 Sreekanth
subbed 4 this 1
I hate the computer generated voice. Please use a human voice it doesn’t matter if you have heavy accent
this video is just amazing!!!
terminator is teaching us rust.
what about CPP memory layout playlist
Thanks for dealing with a neglected topic. Great job!
Simply Great!
