1//! Contains an implementation of JSON serialization format.

3/// A representation of a JSON data. Use it as wrapper to
4/// set a format you want to use for conversion:
5///
6/// ```
7/// // Converts (lazy) data to a Json
8/// use yew::format::Json;
9/// let data: String = r#"{lorem: "ipsum"}"#.to_string();
10/// let dump = Json(&data);
11///
12/// // Converts JSON string to a data (lazy).
13/// let Json(data) = dump;
14/// ```
