WorkerSlot

dualcache_ff::workers

Struct WorkerSlot 

Source 
pub struct WorkerSlot<K, V> { /* private fields */ }
Expand description

Per-worker exclusive slot holding a BatchBuf inside an UnsafeCell.

The WORKER_ID TLS invariant guarantees that only one thread ever accesses any given slot, eliminating the need for any synchronisation primitive on the insert hot-path (zero atomics, zero locks, pure memory write).

Implementations§

Source§

impl<K, V> WorkerSlot<K, V>

Source

pub fn new() -> Self

Source

pub unsafe fn get_mut_unchecked(&self) -> &mut BatchBuf<K, V>

Provides exclusive access to the underlying buffer.

§Safety

The caller must guarantee that only one thread accesses this slot at a time. In DualCache-FF this is enforced by the WORKER_ID TLS invariant.
