Extracting data

Extracting data from the request body is fairly straightforward. All we have to do is define a struct with the attributes we want, and then pass that through as a parameter in the view function. Then, the data from the request body will be serialized to that schema. We can do this by defining the following struct in our json_serialization/to_do_item.rs file:

use serde::Deserialize;
#[derive(Deserialize)]
pub struct ToDoItem {
    pub title: String,
    pub status: String
}

Here, we have used the Deserialize macro. Now that we have this, we can start building our edit view in the views/to_do/edit.rs file. Because the view requires a lot of code, we will be breaking it down into sections. First, we need to import all of the crates that we are going to use:

use actix_web::{web, HttpResponse};
use serde_json::value::Value;
use serde_json::Map;
use super::utils::return_state;
use crate::state::read_file;
use crate::to_do:...
