Function json_with_comments::ser::to_string_pretty

pub fn to_string_pretty<S>(value: S) -> Result<String>
where
    S: Serialize,

Serialize struct S as pretty formatted JSON with comments text. If you want to serialize as minified JSONC text, use to_string instead.

Examples

use serde::Serialize;
#[derive(Serialize)]
struct Country<'a> {
    name: &'a str,
    code: u32,
    regions: Vec<&'a str>,
}
let japan = Country {
    name: "Japan",
    code: 81,
    regions: vec!["Hokkaido", "Kanto", "Kyushu-Okinawa"],
};
let jp = json_with_comments::to_string_pretty(japan).unwrap();
let pretty = r#"{
  "name": "Japan",
  "code": 81,
  "regions": [
    "Hokkaido",
    "Kanto",
    "Kyushu-Okinawa",
  ],
}"#;
assert_eq!(jp, pretty);
