Hey Derek, just wanted to say I bought your course. I didnt need it since I already know python but im curious about all the extra stuff I'll learn The main reason I bought it is because you've been so helpful over the years and your passion is what made me actually want to code

I cannot thank you and commend you enough Derek! 10 years ago I was working full time in construction and part time in landscaping and as a janitor while going to college. I was barely making enough to afford my small room and food. I came across your videos and spent every spare minute I had watching you and practicing everything you did because I loved computers, writing code, and wanted a better life for myself and my eventual family. Fast forward to today and thanks to you I am a full-time software and data engineer that also does BI consulting on the side. I have become successful enough to build a new home for my family, take care of my parents, and take care of my siblings. I haven't stopped learning (hence why I am here learning Rust!) and it's because you're a wonderful teacher that can take many complex topics and ideas and interpret them in a way that allows me and tens of thousands of others to learn and apply. Also because of you, I do everything possible to give back and teach others as best I can. Anyways, thanks for making this content and doing it without cost as you literally helped me to start a career and climb out of poverty. I owe you so much - thank you!

[@derekbanas]

Thank you for taking the time to write such a nice message and making my New Year. Congratulations on all that you accomplished and I wish you and your family all the best! Your message is the reason why I keep making videos.

Awesome! I used your old Rust video way back in the day when first learning Rust in 2019 and as of this month I've been a full-time Rust developer for a year so all's well that ends well. Going to let people know that you've got a new one!

[@mau5atron]

What was interviewing for a Rust role like? I looked into Rust back in 2018 but didn't have enough experience with other languages to understand and be productive with it. I'm halfway through this video and feel like I could jump on a project with Rocket and start building backend web services after learning a bit of Erlang and Go.

[@mithradates]

@@mau5atron In my case the company was just starting to move to Rust and was looking for someone to help with that, plus I had written and recorded a lot of material here on the language so I was sort of pre-tested already. (Also helped that the company is Korean and I live in Korea)

[@mau5atron]

mithradates very cool! I didn’t notice you had content on Rust in Korean. I appreciate the insight. I just subbed :)

[@mithradates]

@@mau5atron Thanks! There's definitely a shortage of material to learn Rust here in Korea so I've been making most of my videos in Korean (have a few English ones to add now though and are making those).

[@MarkusBurrer]

Important note: the if example you are showing is NOT an expression. It's a statement. Expressions ALWAYS return something It the Ternary Operator example you say that you don't need a semicolon after the last statement, but the true and false are actually expressions in this case. Summary: Your if example is a statement and your ternary operator example is an expression. Please don't mix this up

[@containerman17]

Thanks!

[@mojekonto9287]

I had a problem with the last exercise with the thread and the bank account... then I went to chatgpt, pasted my code and told it to correct it for me.... and it DID! Although it used a "move" keyword in one place, and changed the 5.0 into amt, which actually made sense :o I got blown away. Anyway, coming back to the course... it has been great! I learned quite a bit :) Woow, it took me over 10 hours over the course of a few days to complete this 2.5h course.... can't imagine how much time it took Derek to prepare it and record it for us... :o

[@derekbanas]

Thank you for taking the time to tell me it helped and for sharing your journey, which was an interesting one :)

[@TurboXray]

This first part of the tutorial doesn't work at around 12:00 mark in the video. Rust throws a compiler error because of the missing .ok() before the .expect(). Maybe this is a version update difference to Rust since this video was made???

I typically use while loops when the length or number of values is dynamic, and for loops when the length or number of values is static. Also I use them to help ensure the correct user input, and for testing parts of a function repeatedly.

Great video as always, not entirely sure why I watched since I already know rust but I don't regret it.

[@stevematdavies]

Awesome course. One nit pick, your description of Closures is not quite right. You are illustrating a lambda or anonymous function, but a closure is merely a scope which wraps values, that can be passed into other scopes (such as a function as an argument to another function). This is largely achieved in most cases by anonymous functions but these functions are not "closures" in that they merely are functions. The actual scope they contain and give access to is what actually creates the closure (i.e. it "closes the scope in") Many languages allow this construct and many don't particularly rely on anonymous functions, but all rely on first class functions (functions that can be passes as objects). iter() is a very good example of implementing a closure, especially as you illustrated the next() function!

[@johnmahugu3527]

Banas :D awesome thank you very much for this. i am an accomplished scientist now thanks to many of your videos.

[@TomLeg]

At 50:30, you can't use .bytes() to get unicode, or it has limited value. Not sure of the Rust terminology but it should e .cahars() or .graphemes()

Every time I want to start learning Rust, I hit the same place early on that spoils the whole language for me: "do_something.expect("error type message") The only place that .expect("error type message") will EVER make sense in a program is if you actually expect something to break. Any other explanation given is the same result: a better word could have been chosen.

@derek 1:33:11 Need brackets for trait constructor. Also missing dyn keywork and sized self new trait

[@justingolden21]

1:31:08 I like 995 of Rust so far, but this seems super redundant. We're defining Shape which has a constructor for length and width as f32, then we're defining Rectangle which is a struct with length and width as f32, then we're implementing shapre for rectangle and we need a constructor which takes in length and width which are f32 and returns a rectangle and returns a rectnagle with the specified length and width. It shouldn't be necessary to retype "f32" and "length" and "width" and "rectangle" so many times. I wonder if it's possible to do it in a cleaner way, eg.: trait Shape { fn new(length:f32, width:f32) -> Self } struct Rectangle impl Shape { fn new(length, width) -> Self { return rectangle {length, width}; } }

[@TomLeg]

At 58:36 in the discussion about vectors, First you generate a pointer to the second element of vec2, then you get() that same element. This seems like duplication. Accessing vector elements is pretty minor, but why do things twice? DRY, as they say.

[@dynfoxx]

It's get vs []. Get returns an option that's why it can be none. [] returns a reference and panics if it's out of bounds.

[@TattedFaceJoey]

I'm currently at 12:35. I wish you had mentioned that e.g. ': String', ': &str', 'Result', and 'msg:' were actually auto-inserted and the viewer (i.e. me) didn't need to enter them. I was following along and thought you entered them

[@DJDopeB]

With it or without it I'm getting an error. Something like: expected some of 8 tokens. Not sure what it is. I'm stuck 😢

[@tornoutlaw]

@@DJDopeB Same here, probably because we installed a newer cargo/rust version and the syntax has changed since 2022. It compiled for me, when I removed `buf: `, `Result` and `msg:`. Unfortunately, this will have me look for a newer tutorial :/
