Implementations

impl ExpertArena

pub fn new( num_slabs: u32, slots_per_slab: u32, record_stride: usize, ) -> Result<Self>

2026-09-25: Allocate num_slabs * slots_per_slab * record_stride pinned bytes. Fails on a zero dimension, a stride that is not a multiple of 4096, a size overflow, or a device address that differs from the host address.

pub fn num_slabs(&self) -> u32

pub fn slots_per_slab(&self) -> u32

pub fn record_stride(&self) -> usize

pub fn slot_host_ptr(&self, slab: u32, slot: u32) -> Result<*mut u8>

2026-09-25: Host pointer of a slot, where its record is written.

pub fn slot_dev_va(&self, slab: u32, slot: u32) -> Result<u64>

2026-09-25: Device address of a slot.

pub fn base_ptr(&self) -> *mut c_void

2026-09-25: Base of the pinned allocation; with total_bytes it describes the whole arena.

pub fn total_bytes(&self) -> usize
