Struct OperatorSlot 

pub struct OperatorSlot<'scope, T: Timestamp> { /* private fields */ }

A reservation for an operator at a specific position in a parent Scope.

Returned by Scope::reserve_operator and [SubscopeHandle::build]. The slot carries the scope-local index and the worker-unique identifier of the operator-to-be. It must be consumed by OperatorSlot::install before being dropped; dropping an unfilled slot panics, since the parent scope expects the reserved index to eventually be filled.

Implementations

impl<'scope, T: Timestamp> OperatorSlot<'scope, T>

pub fn index(&self) -> usize

The scope-local index reserved for the operator.

pub fn identifier(&self) -> usize

The worker-unique identifier reserved for the operator (used for logging).

pub fn addr(&self) -> Rc<[usize]>

The address (path from the worker root) at which the operator will live.

pub fn install(self, operator: Box<dyn Operate<T>>)

Installs operator at this slot, consuming the slot.
