//! This module provides utilities for working with JSON data.

pub use serde_json::json;
pub use serde_json::to_string as struct_to_string;
pub use serde_json::Result as JsonResult;
pub use serde_json::Value as JsonValue;

/// Converts a `JsonValue` (`serde_json::Value`) to a string
///
/// # Example
///
/// ```rust
/// use krustie::{ Request, Response, StatusCode, request::RequestBody, json::{ get_string_from_json, json } };
///
/// fn post_req(req: &Request, res: &mut Response) {
///   match req.get_body() {
///     RequestBody::Json(body) => {
///       let server_key_option = body.get("server");
///
///       match get_string_from_json(server_key_option).unwrap().as_str() {
///         "Krustie" => {
///           res.status(StatusCode::Ok).body_json(body.clone());
///         },
///         _ => {
///           res.status(StatusCode::try_from(201).unwrap()).body_json(
