Struct RelationDeltaCancellation 

Source 
pub struct RelationDeltaCancellation { /* private fields */ }
Expand description

Tuples canceled at one ordered merge step of a relation-delta batch.

Implementations§

Source§

impl RelationDeltaCancellation

Source

Source

pub fn incoming_direction(&self) -> RelationDeltaDirection

Return the direction of the incoming occurrence that caused the cancellation.

Source

pub fn tuples(&self) -> &CudaBuffer

Borrow the GPU-resident tuples canceled at this merge step.
