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: mod.rs
    path of file: ./repos/ast-grep/crates/cli/src/print
    
    the code of the file until where you have to start completion: mod cloud_print;
mod colored_print;
mod interactive_print;
mod json_print;

use crate::lang::SgLang;
use ast_grep_config::{Fixer, RuleConfi
    
  fn from(arg: ColorArg) -> ColorChoice {
    use ColorArg::*;
    match arg {
      Auto => {
        if atty::is(atty::Stream::Stdout) {
          ColorChoice::Auto
        } else {
          ColorChoice::Never
        }
      }
      Always => ColorChoice::Always,
      Ansi => ColorChoice::AlwaysAnsi,
      Never => ColorChoice::Never,
    }
  }
