pub struct NumaSlabPool { /* private fields */ }

Multi-node slab pool that routes allocations to NUMA-local slabs.

Implementations

impl NumaSlabPool

pub fn from_manifest( manifest: &ReactorPlacementManifest, config: NumaSlabConfig, ) -> Self

Create a pool with one slab per NUMA node identified in the placement manifest.

pub const fn set_hugepage_status(&mut self, status: HugepageStatus)

Override hugepage status after querying the host.

pub fn node_count(&self) -> usize

Number of NUMA nodes in this pool.

pub fn allocate( &mut self, preferred_node: usize, ) -> Option<(NumaSlabHandle, Option<CrossNodeReason>)>

Allocate from the preferred NUMA node, falling back to any node with capacity.

Returns (handle, cross_node_reason) where the reason is Some when the allocation was served from a non-preferred node.

pub fn deallocate(&mut self, handle: &NumaSlabHandle) -> bool

Deallocate a previously allocated handle.

Returns true if deallocation succeeded.

pub fn telemetry(&self) -> NumaSlabTelemetry
