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: indent.rs
    path of file: ./repos/ast-grep/crates/core/src/replacer
    
    the code of the file until where you have to start completion: use crate::source::Content;
use std::borrow::Cow;
use std::cmp::Ordering;
use std::ops::Range;

/**
  This module is for in
    
  fn test_replace_with_indent(target: &str, start: usize, inserted: &str) -> String {
    let target = target.to_string();
    let replace_lines = DeindentedExtract::MultiLine(inserted.as_bytes(), 0);
    let indent = get_indent_at_offset::<String>(&target.as_bytes()[..start]);
    let ret = indent_lines::<String>(indent, replace_lines);
    String::from_utf8(ret.to_vec()).unwrap()
  }
