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/regex/tests
    
    the code of the file until where you have to start completion: #![cfg_attr(feature = "pattern", feature(pattern))]

mod fuzz;
mod misc;
mod regression;
mod regression_fuzz;
mod replace;
#[cfg(feature = "pattern")]
mod searcher;
mod suite_bytes;
mod suite_bytes_set;
mod suite_string;
mod suite_string_set;
