Trait AtomicCounterEntry

pub trait AtomicCounterEntry: Send + Sync {
    // Required methods
    fn resolve(&self) -> Option<AtomicCounter>;
    fn make_storable(strong: &AtomicCounter) -> Self;
    fn needs_pruning() -> bool;
}

This trait enables having prunable and non-pruning value types in the CounterRegistry.

Required Methods

fn resolve(&self) -> Option<AtomicCounter>

resolve this entry to an AtomicCounter instance

fn make_storable(strong: &AtomicCounter) -> Self

Given a new strong AtomicCounter reference, return Self suitable for storing in the counter registry

fn needs_pruning() -> bool

Indicate whether this type of value requires pruning the containing counter registry

Object Safety

This trait is not object safe.

Implementors

impl AtomicCounterEntry for AtomicCounter

AtomicCounter is a direct store of the underlying counter value. No pruning is required for this type of value.

impl AtomicCounterEntry for WeakAtomicCounter

WeakAtomicCounter stores values as weak references and thus requires pruning.
