Struct HazardBag

Source 
pub struct HazardBag {
    head: AtomicPtr<HazardSlot>,
}
Expand description

Global bag (multiset) of hazards pointers. HazardBag.head and HazardSlot.next form a grow-only list of all hazard slots. Slots are never removed from this list. Instead, it gets deactivated and recycled for other Shields.

Fields§

§head: AtomicPtr<HazardSlot>

Implementations§

Source§

impl HazardBag

Source

pub const fn new() -> Self

Source

fn acquire_slot(&self) -> &HazardSlot

Source

fn try_acquire_inactive(&self) -> Option<&HazardSlot>

Find an inactive slot and activate it.

Source

pub fn all_hazards(&self) -> HashSet<*mut ()>

Returns all the hazards in the set.
