The whole **FastAPI** framework is based to satisfy that. Autocompletion works everywhere.

You will rarely need to come back to the docs.

Here's how your editor might help you:

        final SitemapSet sitemapSet = sitemapsHelper.parse(in);

* `breaking`: Breaking Changes
    * Existing code will break if they update the version without changing their code. This rarely happens, so this label is not frequently used.
* `security`: Security Fixes
    * This is for security fixes, like vulnerabilities. It would almost never be used.
* `feature`: Features

If you are building an application or a web API, it's rarely the case that you can put everything in a single file.

**FastAPI** provides a convenience tool to structure your application while keeping all the flexibility.

      int result = getUid(left).compareTo(getUid(right));
      if (result == 0) {
