It isn't really tokio that lets you use the async await syntax. But it is the most commonly used wrapper around the machinery that rust expects when encountering them.

Thank you! I’ve been struggling with this problem for far too long because the examples in the reqwest docs are incomplete fragments 😫

Funny timing that you release this now, I'm starting a project at work to incorporate Rust into my workplace's C++ codebase, and the task I'm doing to prove its worth is replacing (one of) our json format parsers with serde (and binding with cxx).

So far, with very little work Serde does the same work (or better) than rapidjson in 2/3 the time, and that's with buffered input, if I read the whole file to a string first (no networking stuff, all local) it's 10x as fast. In either case it's looking to be a strong win for Rust.

This is a good video for anybody trying to create a JSON over HTTP (REST) client.

One of the things that's tripped me up using Rust is the concept of unwrapping. Would love to see a video explaining it all

This video is worth it's weight in gold.

I think code reviews similar to what the Cherno does for c++ could be a pretty interesting addition to your current content

Awesome video!
Is there any video linking Rust to a sql database?
I’m watching the language book series and haven’t finished it yet rs

If it would cover some error handling like running another function if the request fails it would be perfect.

What VScode extensions do you have? I like the generated text next to some of the code statements showing the result value type.

[mrlectus]

What if i have error response and success response, how would i go about that?

[achuthansajeevan]

Excellent content and very easy to follow. Thanks for the tutorial!!!

How to get the response status code, headers ...?
If we try to json-deserialize a non-json string to a struct, will the library give us a Result or the app will panic?
I guess that the issue with a lot of Rust crates are lack of documentation.

I have request each return a different response (different variables) how can I make structs for this kind of response ?

[sergiuoanes]

Aewsome video! I was looking for something like this. thank you

[ragy]

Been looking for a video JUST like this. Thank you, very helpful 👍

[Franx]

What if the struct of the get response is variable?

[bjugdbjk]

u have an amazing teaching skill buddy !! u made rust so simple !!

[awlc]

Awesome! Can you do a websocket client?

how to access key values from arbitrary json ?
