Struct PhysicalOperatorId 

pub struct PhysicalOperatorId(/* private fields */);

A plan-local physical operator identity assigned in pre-order.

The identity is stable for one physical plan shape and lets planning and execution diagnostics correlate repeated operators without relying on operator names or process-local addresses.

Implementations

impl PhysicalOperatorId

pub const fn from_ordinal(ordinal: usize) -> PhysicalOperatorId

Creates an identity from its pre-order position in the physical plan.

pub const fn ordinal(self) -> usize

Returns the operator’s zero-based pre-order position.
