pub struct BufferPoolThreadCache;Expand description
Utilities for managing the calling thread’s local BufferPool caches.
Internally, each thread owns a sparse Vec<Option<TlsSizeClassCache>>
keyed by SizeClass::class_id, with one per-size-class cache allocated
lazily on first use. Thread exit naturally flushes cached buffers back to
the shared global freelist because TlsSizeClassCache drains itself in
Drop.
This type exists to keep the unsafe TLS access localized. All steady-state
cache operations (pop, push, and refill) go through this facade rather
than free functions over the thread_local! static.
