Struct ResidentRelation 

pub struct ResidentRelation { /* private fields */ }

A fixed-capacity relation whose storage remains stable for a graph lifetime.

Implementations

impl ResidentRelation

pub fn buffer(&self) -> &CudaBuffer

pub fn into_buffer(self) -> CudaBuffer

Consume the stable owner after terminal receipt validation.

This performs no transfer, synchronization, or host-count observation.

pub fn into_buffer_with_observed_schema( self, schema: Schema, ) -> Result<CudaBuffer>

Consume a synchronized final owner with its receipt-selected schema.

This changes metadata only after all captured work is complete and validates that the selected schema has the same physical layout.

pub fn retag_schema_for_capture(&mut self, schema: Schema) -> Result<()>

Retag a cold scratch allocation without changing any device address.

This is only valid before the graph that will use this relation is launched. Captured kernel nodes own copies of their pointer/width arguments; callers must not retag a relation while a launch is in flight. Final head relations must not use this scratch-pool operation.

pub fn capacity(&self) -> u32

pub fn num_rows_device(&self) -> &TrackedCudaSlice<u32>

pub fn record_uses(&self, recorder: &mut LaunchRecorder)

Add every owned allocation to the transaction’s strict recorder.
