Great talk. There is a lot of mixup between percent and percentage points. If the baseline is 2% and the improved score is 4% the increase is not 2% (but 2%pt) or 100%. From 47% to 56% is 19% increase or 9%pt.
@19:10 it would make it clearer if the Heap in L2 and L3 was lower, representing the new address in memory that was allocated, perhaps leaving num pointed at the blank space above. Great talk by the way, as a learner of Rust as the first language, i appreciate the effort.
@@supervaka9584 I started with Python 20 years ago, and that gave me something of a basis for understanding what I am learning as a I learn Rust. That said, Rust could be a great first language if The Book and other resources are changed to introduce systems programming.
Another wonderful talk, I was not aware of this resource but now that I do I will give it a go. My experience with Rustlings was amazing and Test driven development was really new experience for me to try out. It was practical and theoretical in the same time.
The second example does not compile if you desugar the indexing into calls to `index` and `index_mut`. So some of those 33% are probably just not realizing the array index syntax gets special treatment.
That's not true. After desugaring into: **v2.index_mut(0) = 5; let a = **v2.index(0); let b = *v.index(0); It'll all work exactly the same, compiling just fine, and printing "5 5". The reason it works is because of non-lexical lifetimes. Because v2 isn't used after the statement let a = *v2[0];. For example, if you were to add println!("{v2:?}"); at the end of the method, it would no longer compile, because v2 is still used. The only "special" thing about array syntax sugar is that it implicitly dereferences the result of invoking the Index::index, and IndexMut::index_mut methods.
Honestly on the first struct/impl part I was assuming it was going to be some overwrite/hoisting type trick but it was simpler in that it just tells you to stop doing stupid things haha.
As a rust learner I appreciate the effort of improving the learning material in such a thoughtful way 👏

rust is your first programming language?
I like rust too but I think the vast majority of people should start with python or javascript.

21:11 single most important statement of the whole talk? (which is excellent in its entirety)
Are the slides available somewhere?
Great work 👍
This needs to be the way we teah all computer science subjects, in all languages
fantastic talk!
