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: suggest.rs
    path of file: ./repos/gluon/completion/tests
    
    the code of the file until where you have to start completion: #[macro_use]
extern crate collect_mac;

extern crate gluon_base as base;
extern crate gluon_check as check;
extern crate gluon_completion as comp
    
fn suggest_record_field_shorthand() {
    let _ = env_logger::try_init();

    let result = suggest_loc(
        r#"
let abc = 1
let abb = "asd"
let aba = ""
let xyz = 2

{ a, aba }
"#,
        6,
        3,
    );
    let expected = Ok(vec!["abb".into(), "abc".into()]);

    assert_eq!(result, expected);
}
