Struct PinnedCapacity 

pub struct PinnedCapacity<'a> { /* private fields */ }

Pinned snapshot of a CapacityAdaptiveRing’s current capacity backing. Send (an Arc lifetime extension), !Sync (single-owner-at-a-time semantics via std::cell::Cell marker).

Implementations

impl<'a> PinnedCapacity<'a>

pub fn is_still_valid(&self) -> bool

Whether this pin’s capacity backing is still the active backing. One Acquire load on the parent’s generation atom.

pub fn capacity(&self) -> usize

Capacity captured at pin time.

pub fn generation(&self) -> u64

Pin generation captured at pin time.

pub fn ring(&self) -> &Arc<AdaptiveRing>

Direct access to the pinned AdaptiveRing.
