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: never.rs
    path of file: ./repos/rustfmt/tests/source/configs/trailing_comma
    
    the code of the file until where you have to start completion: // rustfmt-trailing_comma: Never
// Trailing comma

fn main() {
    let Lorem { ipsum, dolor, sit, } = amet;
    let Lorem { ipsum, dolor, sit, amet, consectetur, adipiscing } = elit;

    // #1544
    if let VrMsg::ClientReply {request_num: reply_req_num, value, ..} = msg {
        let _ = safe_assert_eq!(reply_req_num, request_num, op);
    
fn main() {
    let Lorem { ipsum, dolor, sit, } = amet;
    let Lorem { ipsum, dolor, sit, amet, consectetur, adipiscing } = elit;

    // #1544
    if let VrMsg::ClientReply {request_num: reply_req_num, value, ..} = msg {
        let _ = safe_assert_eq!(reply_req_num, request_num, op);
        return Ok((request_num, op, value));
    }

    // #1710
    pub struct FileInput {
        input: StringInput,
        file_name: OsString,
    }
    match len {
        Some(len) => Ok(new(self.input, self.pos + len)),
        None => Err(self),
    }
}
