You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: lib.rs
    path of file: ./repos/tools/crates/rome_json_formatter/src
    
    the code of the file until where you have to start completion: mod comments;
pub mod context;
mod cst;
mod format_string;
mod generated;
mod json;
mod prelude;
mod separated;

use crate::comments::JsonCommentStyle;
pub(crate) use crate::context::JsonFormatContext;
use crate::context::JsonFormatOptions;
use crate::cst::FormatJsonSyntaxNode;
use rome_formatter::comments::Comments;
use 
    
    fn smoke_test() {
        let src = r#"

    "b": [1, 2, 3, 4],
    "c": null,
    "d": true,
    "e": false
}
"#;
        let parse = parse_json(src, JsonParserOptions::default());
        let options = JsonFormatOptions::default();

        assert_eq!(
            formatted.print().unwrap().as_code(),
