Struct DialogManager 

pub struct DialogManager { /* private fields */ }

Manages dialog event handlers for browser automation.

The DialogManager allows registering callbacks that are invoked whenever a browser dialog (alert, confirm, prompt) is triggered. It is engine-agnostic: the engine-specific dialog interception logic calls DialogManager::dispatch when a dialog event occurs.

Thread Safety

DialogManager is thread-safe and can be shared across async tasks.

Example

use browser_commander::core::dialog::{DialogEvent, DialogManager};

let mut manager = DialogManager::new();

manager.on_dialog(|event| {
    println!("Got dialog: {:?} - {}", event.dialog_type, event.message);
});

// Simulate dispatching a dialog (engine would call this internally)
let event = DialogEvent::from_str_type("alert", "Hello!", None);
manager.dispatch(&event);

Implementations

impl DialogManager

pub fn new_with_engine(engine: EngineType) -> Self

Create a new DialogManager for the given engine.

pub fn new() -> Self

Create a new DialogManager (engine-independent, for testing/simple use).

pub fn on_dialog<F>(&mut self, handler: F)

where F: Fn(&DialogEvent) + Send + Sync + 'static,

Register a dialog handler.

The handler is called synchronously whenever a dialog event is dispatched. For async handling, dispatch a channel message or use tokio::spawn inside the handler.

Arguments

• handler - A function that receives a DialogEvent reference.

pub fn clear_dialog_handlers(&mut self)

Remove all registered dialog handlers.

pub fn handler_count(&self) -> usize

Get the number of registered handlers.

pub fn dispatch(&self, event: &DialogEvent)

Dispatch a dialog event to all registered handlers.

This is called by the engine-specific integration when a dialog appears. If no handlers are registered, this is a no-op (the engine integration should auto-dismiss the dialog in that case).

Arguments

• event - The dialog event to dispatch.

pub fn engine(&self) -> EngineType

Get the engine type this manager is associated with.

Trait Implementations

impl Clone for DialogManager

fn clone(&self) -> DialogManager

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DialogManager

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for DialogManager

fn default() -> Self

Returns the “default value” for a type.
