In the example with pushing an element to the vector you introduced a bug, when you put last element in the variable there was the last element of the vector before it was modified (not 4), but after you swap lines in the last there will be always 4. That's why when you fight with borrow checker you might introduce bugs in business logic. But in this case I believe unit tests are good option to fix that.

Finally a brief/quick explanation/example for lifetimes! Apparently, I've missed the part about the generic collapsing to the shortest duration among matching arguments each time I've tried to learn. That part of the vid could be its own clip/short. Using the colored vertical lines is a great way to visualize the lifetimes. You could also add inline color to the matching variable references.

Ive never watched anything about rust or memory stuff in general but still understood most of the things you explained. I would say you did an amazing job at explaining it
-
I have just wrote down these rules into anki cards after watching video from your rust playbook's course yesterday. I have repeated these cards already for like 3 times and i can say that starting learning rust through spaced repetition is greatest decision i made and i recommend this way for everybody
-
You explain stuff really well bro, thank you!!
-
Thank you for highlighting these Rust essentials in memory management as well as your clear explanation.
-
Explained both simply and with details. Really good work!
-
Really good teaching by example here. I feel like a lot of the time words themselves fail to illustrate concepts like this. Seeing how it works with actual code really cements it. Please keep making videos like this where you can demonstrate such concepts, thanks!

I tried it the last couple days and I practically fell in love with the language. rustc and rust-analyzer are incredible! And the language itself is amazing once the light bulb switches on in the back of your brain. I'm pumped :D Your channel is a gem by the way! Thanks!!

Wow I can really tell the quality of your content has gone up. Bravo! Good job

Rust players when they stumble upon this video...
-
Really clear and concise! Nice work.
-
Wow.... incredible concise and informative. The line illustrations really helped. I feel like cracking back into rust for some longer running data processing I have to do. Thank you again, looking forward to smart pointers video!
-
Tbh I got like 50% of it as I've never coded in rust. I hope this would be of great value when we start rust in our project next month
-
you are an amazing educator! i look forward to your Rust bootcamp 🦀
-
Wow this was really well explained video of one of the central concepts of Rust!
-
You need to make a course, well explained🙌🏽.
-
11:04 another way to phrase this is that the lifetime annotations here tell the borrow checker that a and b must live at least as long as the returned value needs to live.

a small rusty island of understanding in this youtube, thank yu, keep going!
