Rust Programming Tutorial #42 - Parsing JSON

I tend to use JSON in almost all of my projects, the simple data format is friendly and supported by pretty much every programming language, including Rust. By using the 'serde_json' library you are able to work with JSON - in this video I talk specifically about parsing JSON.

Parsing/decoding JSON can be done in two ways: you can access data using a simple array-like data structure (serde_json::Value) or you can conveniently map the JSON string to an actual programmer-defined struct. In this video I show you both ways.

This is all thanks to the serde_json library, take a look and say thank you here:

Hey man, just finished watching this series. As a JS dev looking to learn some Rust, this was a great way to get my feet wet. Thanks for making these!

[AlfredLotsu]

This playlist has been really great thank you!

[NeotenicApe]

This was an incredible series of videos! I feel a void now that I've finished.
Please make more if you have the time and energy!

Awesome series! If you are going to keep making videos about this that would be awesome!

[LakshmipathiG]

Just completed this series. Excellent! thank you for your time and effort!

[lifehackspro]

What a great series! Please make more about Rust ❤

[PseudoDope]

just got to the end wish there was more

May i suggest that you showcase RON? as it's a serialization format specifically for rust. very similar to JSON, but it let's you store structs, enums etc.

[crowncrow]

Well I have as well just finished the series, thank you for the nice tutorials, and to the viewers thanks for the helpfull comments :)

Great series, watched all except this video.

Beautiful tutorial playlist!!! One questions please.. i have as code editor VSCode, and i want install Atom. How is name of the extension rust-analyzer by VSCode, relative to Atom?

[hueseyinguendogan]

Could you make a video about how we can append to a specific field of a json file?

[bjrnsen]

anyone else hear "40 second rust tutorial"?

What if you have a nested Json with an array? How would you define a struct for that? (for example when defining a Tshirt that has multiple colors and sizes )

[thelinuxgamelab]

Great video, really helpful but how to deal with nested JSONs ? as in this example it was just 1 person. But if they are many in a single json file which are usually labelled as 0:, 1: each containing block of data.

[merkg]

Thank you very much. Very informative vide

[matthewbaynham]

What if you have a more complex data structure, for example if the person objects has an attribute wardrobe?

So for each person you have the data items Name, Age, is_male, and a vector structure (or other container) with red shirt, blue shirt, black trousers.

The first part of this video is interesting however I would still need to get the response from a reqwest::Client object to be a string. So how would I convert reqwest::Client response to a string?
