QUESTION
I'm reading the examples of actix-web, but as I am quite new to Rust I am having some issues understanding how to adapt the code to my needs.

, I want to parse the payload and return a JsonValue
. I can't figure out how to change this function to return the JsonValue
rather than a HttpResponse
.

to a string or bytes, then you can set it as the HttpResponse
body. You can not directly return a JsonValue
instead of box because the request body reading process is asynchronous.
