Module query 

Runtime-API queries: pointer attributes, device properties, kernel attributes. Typed wrappers around the cuda*GetAttributes / cudaGetDeviceProperties family.

Structs

DeviceProperties

Subset of cudaDeviceProp fields most users care about. The full C struct is ~1 KB with fields that are rarely accessed — we surface the hot-path ones and keep a reserved _raw slot for the whole buffer so advanced users can cast through.

PointerAttributes

Typed view over cudaPointerAttributes.

Enums

MemoryType

Memory kind reported by pointer_attributes.

Functions

device_properties

Fetch a typed subset of cudaDeviceProp for device.

func_attributes^⚠

Query a kernel’s register / shared-memory / PTX-version metadata. func_symbol is a const void* — the address of the kernel symbol as used by cudaLaunchKernel (or crate::Kernel::as_launch_ptr).

pointer_attributes

Query what CUDA knows about ptr. On pointers CUDA has never seen (plain host malloc, returned from C libraries) this returns MemoryType::Unregistered.
