rustHow to format json to string in Rust

The serde_json crate provides a to_string method to format a json object to a string.

Example code:

use serde_json::json;

let json_object = json!({
    "name": "John Doe",
    "age": 30
});

let json_string = json_object.to_string();

Output

{"name":"John Doe","age":30}

Explanation:

• use serde_json::json;: imports the json macro from the serde_json crate
• let json_object = json!({...});: creates a json object from the given data
• let json_string = json_object.to_string();: formats the json object to a string
