Struct DraftTracker 

pub struct DraftTracker { /* private fields */ }

Tracks in-flight drafts across channels and throttles updates.

Implementations

impl DraftTracker

pub fn new(update_interval_ms: u64) -> Self

pub async fn start( &self, key: DraftKey, initial_text: &str, channel: &Arc<dyn Channel>, ) -> Result<Option<String>>

Start a new draft. Calls channel.send_draft() and tracks the returned message ID.

Returns Ok(message_id) if the channel supports drafts and created one, or Ok(None) if the channel does not support drafts.

pub async fn update( &self, key: &DraftKey, text: &str, channel: &Arc<dyn Channel>, ) -> Result<bool>

Update an in-flight draft with new text.

Respects the throttle interval — if called too frequently, the text is buffered and only the latest version is sent when the interval elapses. Returns true if an update was actually sent to the channel.

pub async fn finalize( &self, key: &DraftKey, final_text: &str, channel: &Arc<dyn Channel>, ) -> Result<()>

Finalize a draft — sends the final text and removes tracking.

pub async fn cancel( &self, key: &DraftKey, channel: &Arc<dyn Channel>, ) -> Result<()>

Cancel a draft — removes tracking and notifies the channel.

pub async fn has_draft(&self, key: &DraftKey) -> bool

Check if a draft is currently tracked for the given key.

pub async fn active_count(&self) -> usize

Get the number of active drafts.

pub async fn flush( &self, key: &DraftKey, channel: &Arc<dyn Channel>, ) -> Result<bool>

Flush a pending update — sends the latest buffered text regardless of throttle.
