Struct Engine 

pub struct Engine {
    pub store: Arc<Store>,
    pub github: Option<Arc<dyn GithubApi>>,
    /* private fields */
}

Fields

store: Arc<Store>

github: Option<Arc<dyn GithubApi>>

Optional GitHub API client. None when no token is configured.

Implementations

impl Engine

pub fn new(store: Arc<Store>) -> Arc<Self>

pub fn new_with_github(store: Arc<Store>, token: String) -> Arc<Self>

pub fn new_with_github_api( store: Arc<Store>, github: Arc<dyn GithubApi>, ) -> Arc<Self>

Construct an Engine with a caller-supplied GithubApi — the dependency-injection seam tests use to drive the GitHub-enrichment poller against a fake instead of the real network.

pub async fn register_stream(&self, session_id: SessionId) -> Receiver<()>

Cancel any running FIFO reader for session_id and return a fresh cancellation receiver for the new reader. Call this at the top of every start_streaming invocation.

pub fn emit(&self, event: Event)

pub fn subscribe(&self) -> Receiver<Event>

pub async fn register_pty_writer( &self, session_id: SessionId, writer: UnboundedSender<Vec<u8>>, )

pub async fn get_pty_writer( &self, session_id: &str, ) -> Option<UnboundedSender<Vec<u8>>>

pub async fn remove_orchestrator(&self, orchestrator_id: &str) -> Result<()>

Kill all worker sessions belonging to an orchestrator, delete from DB, emit events.

pub async fn remove_session(&self, session_id: &str) -> Result<()>

Kill the tmux session and delete it from the DB entirely.

pub async fn send_to_session( &self, session_id: &str, message: &str, ) -> Result<()>

Send a text message to the agent running in a session’s tmux window. The message is injected as keyboard input — the agent sees it as typed text. Returns Ok(()) if the tmux send succeeded; returns an error if the session has no active tmux window or tmux is unavailable.

pub async fn terminate_session(&self, session_id: &str) -> Result<()>

Kill the tmux session, mark it Terminated in the DB, and emit SessionUpdated.

pub async fn cleanup_session(&self, session_id: &str) -> Result<()>

Kill the tmux session (best-effort), remove its worktree/artifacts, and mark it Done in the DB. Called automatically when a PR is merged. Emits SessionUpdated. Mirrors remove_session’s worktree and artifact cleanup so the record isn’t deleted here but still stops leaking a checked-out worktree and per-session hook files.
