Module domain_manager 

CDP Domain Manager

Centralized helper that enables and disables Chrome DevTools Protocol domains.

Design Goals

1. Required Domains Managed Automatically: Core domains such as Page, Runtime, DOM, and Network can be enabled up-front and stay active for the lifetime of the page (RAII-style).
2. Optional Domains On Demand: Optional domains like Fetch, Performance, and CSS expose explicit enable/disable helpers so they are activated only when needed.
3. Guard Against Duplicate Operations: Internal state tracks each domain so repeated enable/disable calls become no-ops.
4. Resource Efficiency: Domains remain disabled until requested, keeping browser overhead low.

Examples

// Required domains (Page, Runtime, DOM, Network) are enabled when the page is created.

// Enable optional domains as needed.
page.domain_manager.enable_fetch_domain().await?;
page.domain_manager.enable_performance_domain().await?;

// Disable optional domains to free resources once finished.
page.domain_manager.disable_fetch_domain().await?;
page.domain_manager.disable_performance_domain().await?;

// When the page is dropped, all domains are cleaned up automatically.
