Trait Handler 

pub trait Handler:
    Send
    + Sync
    + 'static {
    // Required methods
    fn handle_events(&self, event: TradingViewDataEvent, message: &[Value]);
    fn handle_quote_data(&self, message: &[Value]);
    fn handle_series_data(
        &self,
        event: TradingViewDataEvent,
        messages: &[Value],
    );
    fn notify_error(&self, error: Error, message: &[Value]);
}

Core event handler trait — object-safe, supports Arc<dyn Handler>.

Unlike v1, this trait does not require Clone or a new() constructor. Use HandlerFactory for construction and Arc<dyn Handler> when shared ownership is needed.

Required Methods

fn handle_events(&self, event: TradingViewDataEvent, message: &[Value])

Called when a TradingView data event is received.

fn handle_quote_data(&self, message: &[Value])

Called when quote data is received (e.g., price updates).

fn handle_series_data(&self, event: TradingViewDataEvent, messages: &[Value])

Called when series/historical data is received.

fn notify_error(&self, error: Error, message: &[Value])

Called when an error occurs in the WebSocket or command pipeline.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
