Required Associated Types§

Source

type Orchestrator: Borrow<SessionManager<Self>> + Send + Sync

Required Methods§

Source

fn get_info(&self) -> Cow<'_, DeviceInfo>

Called to get block/partition information.

Source

fn spawn_session(&self, session: Arc<Session<Self>>)

Start running a new session. The interface must ensure that Session::run is called on a different thread.

Source

fn on_requests(&self, requests: &[Request])

Starts a batch of requests. The implementation may block if there are too many in-flight requests, providing pushback. The interface is responsible for eventually calling SessionManager::complete_request for each request (even during server shutdown).

Implementations are responsible for checking that request block ranges fall within valid device/partition bounds, and completing with zx::Status::OUT_OF_RANGE if out of bounds.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
