Implementations

impl SlabCache

pub const fn new(size_class: SizeClass) -> Self

pub fn alloc_object<const PAGE_SIZE: usize>(&mut self) -> Option<usize>

Try to allocate one object. Returns Some(obj_addr) or None if no slabs available.

pub fn dealloc_object<const PAGE_SIZE: usize>( &mut self, obj_addr: usize, ) -> CacheDeallocResult

Free an object back to this cache (local CPU path — under lock).

Returns whether the slab should be returned to the page allocator.

pub fn add_slab(&mut self, base: usize, bytes: usize, owner_cpu: u16)

Register a newly allocated slab page (from the buddy allocator).
