Trait Implementations

impl Channel for NullChannel

fn name(&self) -> &str

Channel name (e.g., “telegram”, “discord”, “cli”)

fn start<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<Receiver<IncomingMessage>>> + Send + 'async_trait>>

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

Start receiving messages. Returns a receiver for incoming messages.

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

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

Send a message through this channel. Returns an optional message ID for tracking/editing.

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

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

Stop the channel gracefully.

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

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

Send a typing indicator (or equivalent) to the user.

fn send_media<'life0, 'async_trait>( &'life0 self, media: OutgoingMedia, ) -> Pin<Box<dyn Future<Output = Result<Option<String>>> + Send + 'async_trait>>

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

Send an attachment.

fn supports_media(&self) -> bool

Whether send_media will do anything for this channel. Callers that can fall back to text should check this instead of sending and catching.

fn edit<'life0, 'life1, 'life2, 'life3, 'async_trait>( &'life0 self, _chat_id: &'life1 str, _message_id: &'life2 str, _new_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,

Edit a previously sent message if the channel supports it.

fn as_draft(&self) -> Option<&dyn DraftChannel>

Live draft support, if this channel implements it.
