Struct AtomicL2Entry

pub(super) struct AtomicL2Entry(AtomicU64);

Internal actual type of L2 entries.

Using atomic allows flushing L2 tables from the cache while they are write-locked.

Tuple Fields

0: AtomicU64

Implementations

impl AtomicL2Entry

fn get(&self) -> L2Entry

Get the contained value.

unsafe fn swap(&self, l2e: L2Entry) -> L2Entry

Exchange the contained value.

Safety

Caller must ensure that: (1) No reader sees invalid intermediate states. (2) Updates are done atomically (do not depend on prior state of the L2 table), or there is only one writer at a time.
