Struct libp2prs_swarm::metrics::metricmap::MetricMap

pub struct MetricMap<K, V> { /* fields omitted */ }

MetricMap is a lock-free hash map that supports concurrent operations.

Implementations

impl<K, V> MetricMap<K, V> where
    K: Eq + Hash + Clone + Debug,
    V: Clone + Display, 

pub fn new() -> Self

Create a new MetricMap

pub fn store_or_modify<F: Fn(&K, &V) -> V>(
    &self,
    key: &K,
    value: V,
    on_modify: F
)

If map contains key, replaces original value with the result that return by F. Otherwise, create a new key-value and insert.

pub fn load(&self, key: &K) -> Option<V>

pub fn iterator(&self) -> Option<IntoIter<K, V>>

Return an iterator

Trait Implementations

impl<K, V> Debug for MetricMap<K, V>

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

Formats the value using the given formatter.

impl<K, V> Default for MetricMap<K, V> where
    K: Eq + Hash + Clone + Debug,
    V: Clone + Display, 

pub fn default() -> Self

Returns the "default value" for a type.
