Type Alias DashMapStateStore 

pub type DashMapStateStore<K> = DashMap<K, InMemoryState>;

A concurrent, thread-safe and fairly performant hashmap based on DashMap.

Aliased Type

pub struct DashMapStateStore<K> { /* private fields */ }

Trait Implementations

impl<K: Hash + Eq + Clone> ShrinkableKeyedStateStore<K> for DashMapStateStore<K>

fn retain_recent(&self, drop_below: Nanos)

Remove those keys with state older than drop_below.

fn shrink_to_fit(&self)

Shrinks the capacity of the state store, if possible.

fn len(&self) -> usize

Returns the number of “live” keys stored in the state store.

fn is_empty(&self) -> bool

Returns true if self has no keys stored in it.

impl<K: Hash + Eq + Clone> StateStore for DashMapStateStore<K>

type Key = K

The type of key that the state store can represent.

fn measure_and_replace<T, F, E>(&self, key: &Self::Key, f: F) -> Result<T, E>

where F: Fn(Option<Nanos>) -> Result<(T, Nanos), E>,

Updates a state store’s rate limiting state for a given key, using the given closure.
