Struct DomainRegistry 

pub struct DomainRegistry<H: DomainHandler> { /* private fields */ }

Registry of CDP domain handlers. Thread-safe (Mutex-protected). Generic over handler type H — enables enum dispatch (H=DomainDispatch) for zero-vtable overhead.

Implementations

impl<H: DomainHandler> DomainRegistry<H>

pub fn new() -> Self

pub fn register(&self, handler: H) -> Result<(), String>

Register a DomainHandler. Returns Err if a handler with the same domain_name is already registered (REQ-CDS-006 C5: no overwrite).

pub fn dispatch_command( &self, method: &str, params: Value, event_sender: &dyn EventSender, ) -> Option<Result<Value, CdpError>>

Dispatch a command to the appropriate DomainHandler. Extracts domain from method (e.g. “Page.navigate” → “Page”).

pub fn notify_session_created(&self, domain: &str, session_id: &str)

Notify the DomainHandler for the given domain that a session was created.

pub fn notify_session_destroyed(&self, domains: &[String], session_id: &str)

Notify all DomainHandlers for the given domains that a session was destroyed.

pub fn has_domain(&self, domain: &str) -> bool

Check if a domain is registered.

Trait Implementations

impl<H: DomainHandler> Default for DomainRegistry<H>

fn default() -> Self

Returns the “default value” for a type.

impl<H: DomainHandler + 'static> RegistryDispatch for DomainRegistry<H>

Blanket impl: any DomainRegistry<H> is a RegistryDispatch.

fn dispatch_command( &self, method: &str, params: Value, event_sender: &dyn EventSender, ) -> Option<Result<Value, CdpError>>

Dispatch a CDP command. Returns None if domain not found.

fn notify_session_created(&self, domain: &str, session_id: &str)

Notify the handler for domain that a session was created.

fn notify_session_destroyed(&self, domains: &[String], session_id: &str)

Notify handlers for the given domains that a session was destroyed.

fn has_domain(&self, domain: &str) -> bool

Check if a domain is registered.

fn as_any(&self) -> &dyn Any

Downcast support — allows callers to recover the concrete registry type.

fn dispatch_message( &self, msg: &CdpMessage, ws_target_id: &str, event_sender: &dyn EventSender, ) -> Option<Result<Value, CdpError>>

Dispatch with full routing context: the incoming message (including its optional sessionId for flattened browser sessions) plus the WS session’s own target id (from the /devtools/page/<id> URL, or the browser pseudo-target for /devtools/browser connections).
