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: helpers.rs
    path of file: ./repos/ruff/crates/ruff_linter/src/rules/isort
    
    the code of the file until where you have to start completion: use ruff_python_ast::{PySourceType, Stmt};
use ruff_python_parser::{lexer,
    
pub(super) fn has_comment_break(stmt: &Stmt, locator: &Locator) -> bool {
    // Starting from the `Stmt` (`def f(): pass`), we want to detect patterns like
    // this:
    //
    //   import os
    //
    //   # Detached comment.
    //
    //   def f(): pass

    // This should also be detected:
    //
    //   import os
    //
    //   # Detached comment.
    //
    //   # Direct comment.
    //   def f(): pass

    // But this should not:
    //
    //   import os
    //
    //   # Direct comment.
    //   def f(): pass
    let mut seen_blank = false;
    for line in locator.up_to(stmt.start()).universal_newlines().rev() {
        let line = line.trim_whitespace();
        if seen_blank {
            if line.starts_with('#') {
                return true;
            } else if !line.is_empty() {
                break;
            }
        } else {
            if line.is_empty() {
                seen_blank = true;
            } else if line.starts_with('#') || line.starts_with('@') {
                continue;
            } else {
