Rust Programming Tutorial #31 - Hash Maps (HashMap)

By using the HashMap struct in Rust, you can store a collection of Key-Value pairs. This is a common data structure found across many languages for simple and easy to use data storage.

In this video we look at some of the methods you can use on a HashMap and ways you can use it.

I'm so happy this exists. This is the best beginner tut playlist I have found, for Rust. Awesome work dude!

Good work mate, keep up. I love the short tutorials. Cheers!

Seems silly, but what happens to the order of items in HashMap? When you run throw it in a loop, they're coming on screen in a different order every time, if I'm not mistaken

Hi dcode, Can you make a video how to manipulate json as variables in rust. what i mean when i do request. how to extract the data from respond and put some keys in variable then can do some calculation?

How is a hash map different than a specialized tuple? Is it just the methods you can implement? Thanks for all your hard work. The videos are great.
