Struct RefreshCache

pub struct RefreshCache<K, V, R> { /* private fields */ }

A RefreshCache provides a simple interface for caching values with a time-to-live policy for any type that maps a key to a value asynchronously

This is a replacment for directly using LightCache with a TtlPolicy and calling LightCache::get_or_try_insert everywhere

Implementations

impl<K, V, R, E> RefreshCache<K, V, R>

where K: Copy + Eq + Hash, V: Clone + Sync, R: Refresher<K, V, Error = E>,

pub fn new(refresh: R, ttl: Duration) -> Self

pub async fn get(&self, key: K) -> Result<V, R::Error>
