Struct MemSwapStore 

pub struct MemSwapStore { /* private fields */ }

The generic paging core, lifted to atlas-tier (CUDA- and verbs-free). Re-exported under the atlas_tier names (no historical aliases). Host-RAM SwapStore over a HashMap. Records live in ordinary heap memory — the “swap” tier when no NVMe directory is configured (unbounded, still LRU-ordered by the residency).

Implementations

impl MemSwapStore

pub fn new(record_bytes: usize) -> MemSwapStore

Trait Implementations

impl SwapStore for MemSwapStore

fn record_bytes(&self) -> usize

fn write_record(&mut self, disk_slot: usize, bytes: &[u8]) -> Result<(), Error>

fn read_record(&self, disk_slot: usize, out: &mut [u8]) -> Result<(), Error>

fn discard_record(&mut self, disk_slot: usize)

Optional: reclaim disk space for a freed slot (default no-op; a hole in a preallocated file is fine — the free-list reuses the index).
