Let's Learn Rust: Vectors and Hash Maps

It probably comes as no surprise that Rust implements the two most popular data structures in computing: Vectors and Hash Maps. You'll want to learn these and learn them well as you'll use them in most programs you build.

Hope you enjoyed the video!

Fast, concise, no bull shit. Subscribed.

It's interesting to see how different languages do things. Thank you! Great work as always.

[HaroldR]

Just getting into Rust, thank you so much for these videos! Your content is always really clear and straight to the point.

[meekmtck]

I have to echo a lot of other folk. As an intermediate Rust tinkerer, please make more Rust videos. The way you go about providing information is great. You dont talk just to hear yourself talk and get to the point. No irrelevant info! Id love to see you post more Rust videos and gradually dive deeper into this interesting language! Thanks Boss.

For the HashMap.get(element).unwrap() maybe the such element") is a cleaner solution.

[swoopertr]

load more advanced RUST videos. love it. carry on.

I love this content!

Also I would like to ask a question. Can you make a video explaining break points and how to use them? I think that they are really important in programming when a bug occurs or when the result is not what you expected, but I never understood how to use them ahah. I thibk it would be a nice video from you, what do you think, will you ever do one? If not it's fine. :)

I'd also like to add my voice to the requests for more Rust videos from you! Perhaps you could explain `unwrap()`? A video on ownership/borrowing would also be super helpful.

It is unbelievable how this has below 5k views. This is extremely good content, please keep it up!

[joeyvico]

One very good series. Short concise and straight to the point. I like it. Please, keep them coming. Youtube is a little short on good Rust tutorials

[ZyklonV]

Yet another way to safely act only when you do get the value you're looking for is the handy `if let` statement:
if let Some(n) = numbers.get("two") {
println!(n);
}

[kaloyanhristov]

Hey man, top content! Do you plan to continue the Rust series anytime soon?

[Adam-cnib]

I'm glad I found ur channel :). There's not a lot of Rust youtubers right now...

[JamesSmith-cmsg]

Hi thanks for these Rust lessons, will you add more?

[HasanIbraheem]

I like your rust videos but as someone who's used rust for several years now I feel there there were some things that you glossed over or didn't explain very well. (For instance that you need to implement the Hash and Eq traits to be a key, so floats are not allowed). I also would like to mention that the "with_capacity" function is very useful for creating vectors or maps with a predefined size.

[tomglod]

Hey are you planning on doing any more videos in this series?

[tanmaygaurkar]

let mut text: Hashmap<&str, i32>=Hashmap::new();
| ^ expected one of `:`, `;`, `=`, `@`, or `|`
Why this error has occured plz help ?

[subodhadhikari]

Can you please make a video on wifi penetration

[superhussein]

is rust good for promoting neo nazism?
