Struct EventEmitter 

pub struct EventEmitter<H> { /* private fields */ }

Event emitter for managing typed event handlers.

This provides a thread-safe way to register, invoke, and remove event handlers of a specific type.

Implementations

impl<H> EventEmitter<H>

pub fn new() -> Self

Create a new empty event emitter.

pub async fn add(&self, handler: H) -> HandlerId

Add a handler and return its ID.

pub async fn remove(&self, id: HandlerId) -> bool

Remove a handler by its ID.

Returns true if a handler was removed, false if the ID was not found.

pub async fn clear(&self)

Remove all handlers.

pub async fn is_empty(&self) -> bool

Check if there are any handlers registered.

pub async fn len(&self) -> usize

Get the number of registered handlers.

impl EventEmitter<PageEventHandler>

pub async fn emit(&self, page: Page)

Emit an event to all page handlers.

Each handler is called with a clone of the page.

impl EventEmitter<CloseEventHandler>

pub async fn emit(&self)

Emit a close event to all handlers.

Trait Implementations

impl<H> Default for EventEmitter<H>

fn default() -> Self

Returns the “default value” for a type.
