Struct ManagedParallelSession

Source

pub struct ManagedParallelSession { /* private fields */ }

Expand description

High-level managed parallel session: owns the single multiplexed control connection and hands out one ParallelSubSession per server-created sub-session for the driver to run concurrently.

Implementations§

Source §

impl ManagedParallelSession

Source

pub async fn start_with_cancel( url: String, api_key: String, create: CreateBacktestSessionRequest, parent_cancel: CancellationToken, ) -> Result<Self, ManagedSessionError>

Start a parallel session tied to a caller-owned cancellation token.

Source

pub fn control_session_id(&self) -> &str

The server-assigned id grouping these sub-sessions (used for reconnect).

Source

pub fn take_sub_sessions(&mut self) -> Vec<ParallelSubSession>

Take the sub-sessions for driving. Returns them once; subsequent calls yield an empty vec.

Source

pub async fn shutdown(self)

Cancel the session and join the control task.
