Module memory 

CUDA memory management

This module provides GPU memory management with budget enforcement. It wraps cudarc’s allocation functions and tracks total allocated memory.

Structs

ArrowDeviceColumn

CudaBuffer

Column-oriented GPU buffer

DlpackColumn

GpuMemoryManager

GPU memory manager with budget enforcement

RuntimeAllocBlock

Owned handle for a raw allocation routed through GpuMemoryManager::alloc_raw / the v0.6 device runtime.

TrackedCudaSlice

A CudaSlice that automatically updates GpuMemoryManager allocation tracking on drop. Inner slice is wrapped in ManuallyDrop so the [Backing] enum can choose between cudarc-side free (legacy) and runtime-side deallocate (migrated) without producing a double-free.

Enums

CudaColumn

Column data stored in device memory.

Functions

validate_logical_row_count
