Trait Implementations

impl SendCallback for NoOpSendCallback

fn on_pending(&self, _chat_id: &str, _msg: &Message)

Message created and added to STATE as pending.

fn cancel_token(&self, _pending_id: &str) -> Option<Arc<AtomicBool>>

The flag a cancel flips for this pending message, if the client keeps one. The uploader polls it between progress ticks, so a cancel lands at once even while nothing is moving.

fn on_upload_progress( &self, _pending_id: &str, _percentage: u8, _bytes_sent: u64, ) -> Result<(), String>

File upload progress. Return Err(“…”) to cancel the upload.

fn on_upload_complete( &self, _chat_id: &str, _pending_id: &str, _attachment_id: &str, _url: &str, )

Upload complete, attachment URL now available.

fn on_upload_stage(&self, _pending_id: &str, _stage: &str, _pct: Option<u8>)

What an upload is doing before its bytes move: sealing ("encrypting", with its percentage when it is streamed) or getting underway ("starting").

fn on_sent(&self, _chat_id: &str, _old_id: &str, _msg: &Message)

Message successfully delivered to at least one relay. old_id is the pending ID, msg has the real event ID.

fn on_failed(&self, _chat_id: &str, _old_id: &str, _msg: &Message)

Message delivery failed after all retry attempts.

fn on_persist(&self, _chat_id: &str, _msg: &Message)

Persist message to database. Default is no-op. Tauri implements this to call save_message + save_slim_chat.
