Trait Implementations

impl<K> CounterTrait<K> for Counter<K>

where K: Send + Sync + Hash + Eq + Debug + Clone,

Counter caches the hotspot parameter

fn add(&self, key: K, value: u64)

add add a value to the cache, Updates the “recently used”-ness of the key.

impl<K> Debug for Counter<K>

where K: Send + Sync + Hash + Eq + Debug + Clone + 'static + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<K> Default for Counter<K>

where K: Send + Sync + Hash + Eq + Debug + Clone,

fn default() -> Counter<K>

Returns the “default value” for a type.
