Struct GmailPushChannel 

pub struct GmailPushChannel {
    pub config: GmailPushConfig,
    pub tx: Arc<Mutex<Option<Sender<ChannelMessage>>>>,
    /* private fields */
}

Gmail Pub/Sub push notification channel.

Incoming messages arrive via webhook (POST /webhook/gmail) and are dispatched to the agent. The listen method registers the Gmail watch subscription and periodically renews it.

Fields

config: GmailPushConfig

tx: Arc<Mutex<Option<Sender<ChannelMessage>>>>

Sender half injected by the gateway to forward webhook-received messages.

Trait Implementations

impl Channel for GmailPushChannel

fn name(&self) -> &str

Human-readable channel name

fn send<'life0, 'life1, 'async_trait>( &'life0 self, message: &'life1 SendMessage, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Send a message through this channel

fn listen<'life0, 'async_trait>( &'life0 self, tx: Sender<ChannelMessage>, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Start listening for incoming messages (long-running)

fn health_check<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = bool> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Check if channel is healthy

fn start_typing<'life0, 'life1, 'async_trait>( &'life0 self, _recipient: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Signal that the bot is processing a response (e.g. “typing” indicator). Implementations should repeat the indicator as needed for their platform.

fn stop_typing<'life0, 'life1, 'async_trait>( &'life0 self, _recipient: &'life1 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Stop any active typing indicator.

fn supports_draft_updates(&self) -> bool

Whether this channel supports progressive message updates via draft edits.

fn supports_multi_message_streaming(&self) -> bool

Whether this channel supports multi-message streaming delivery, where the response is sent as multiple separate messages at paragraph boundaries as tokens arrive from the provider.

fn multi_message_delay_ms(&self) -> u64

Minimum delay (ms) between sending each paragraph in multi-message mode. Channels should override this to avoid platform rate limits.

fn send_draft<'life0, 'life1, 'async_trait>( &'life0 self, _message: &'life1 SendMessage, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Send an initial draft message. Returns a platform-specific message ID for later edits.

fn update_draft<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, _text: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait,

Show a progress/status update (e.g. tool execution status). Channels can display this in a status bar rather than in the message body. Default: no-op (progress is ignored).

fn finalize_draft<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _recipient: &'life1 str, _message_id: &'life2 str, _text: &'life3 str, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Cancel and remove a previously sent draft message if the channel supports it.

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,
