Module engine 

Low-level engine helpers for launching the Playwright driver and building Chromium launch options.

This module sits between the high-level session types in crate::fetcher and the raw Playwright Rust bindings. It has two public functions:

• build_launch_options – assembles the full set of Chromium CLI flags, proxy settings, executable path, and channel from a BrowserConfig, merging in stealth flags when requested and filtering out any harmful automation-revealing arguments.

• launch_playwright – starts the Playwright driver process. This must be called once before any browser can be launched or connected to.

You typically do not call these functions directly; [DynamicSession::start] and [StealthySession::start] use them internally.

Functions

build_launch_options
