Struct SlabHdr 

pub(super) struct SlabHdr {
    keg: Arc<UmaKeg>,
    items: *mut u8,
    flags: SlabFlags,
    state: Mutex<SlabState>,
    refs: AtomicUsize,
}

Implementation of uma_slab_head.

Fields

keg: Arc<UmaKeg>

items: *mut u8

flags: SlabFlags

state: Mutex<SlabState>

This MUST be locked after everything else (e.g. keg state and zone state) otherwise it will cause a deadlock.

refs: AtomicUsize

Implementations

impl SlabHdr

pub unsafe fn new( keg: Arc<UmaKeg>, flags: SlabFlags, items: *mut u8, len: usize, ) -> Self

Safety

• items cannot be null.
• len must be a number of elements of the array at items.
