    StreamEvent(Box<dyn Fn(&MessageStreamEvent, &Message) + Send + Sync>),
    Text(Box<dyn Fn(&str, &str) + Send + Sync>),
    Message(Box<dyn Fn(&Message) + Send + Sync>),

}

Event handlers for different types of events.

This enum encapsulates the different callback types that can be registered with MessageStream for handling various events during streaming.

Variants

StreamEvent(Box<dyn Fn(&MessageStreamEvent, &Message) + Send + Sync>)

Handler for stream events - receives event and current message snapshot

Text(Box<dyn Fn(&str, &str) + Send + Sync>)

Handler for text deltas - receives delta text and current accumulated text

Message(Box<dyn Fn(&Message) + Send + Sync>)

Handler for complete messages

FinalMessage(Box<dyn Fn(&Message) + Send + Sync>)

Handler for the final message when stream completes

Error(Box<dyn Fn(&AnthropicError) + Send + Sync>)

Handler for errors

End(Box<dyn Fn() + Send + Sync>)

Handler for stream end

Connect(Box<dyn Fn() + Send + Sync>)

Handler for connection established

Abort(Box<dyn Fn(&AnthropicError) + Send + Sync>)

Handler for stream abort
