Function json_with_comments::ser::to_file

pub fn to_file<S>(value: S, file: &mut File) -> Result<()>
where
    S: Serialize,

Serialize struct S as a minified JSON with comments text of the given file. If you want to serialize as pretty formatted JSONC text, use to_file_pretty instead.

Examples

use serde::Serialize;
#[derive(Serialize)]
struct Product {
    name: String,
    price: u32,
}
let path = std::path::Path::new("tests/data/product_minify.jsonc");
if path.exists() {
    std::fs::remove_file(path).unwrap();
}
let mut file = std::fs::File::create(path).unwrap();
let product = Product { name: "candy".to_string(), price: 100 };
json_with_comments::to_file(product, &mut file).unwrap();
assert_eq!(std::fs::read_to_string(path).unwrap(), r#"{"name":"candy","price":100}"#);
