Struct CacheAsync 

pub struct CacheAsync<K, V>
where
    K: Hash + Eq + Clone,
{ /* private fields */ }

Implementations

impl<K, V> CacheAsync<K, V>

where K: Hash + Eq + Clone,

Similar to Cache, but using async RwLock

pub fn new(generator: impl Fn(&K) -> V + 'static + Sync) -> Self

where K: Hash + Eq,

Create a new cache using the given generator function

pub async fn get_if(&self, key: &K) -> Option<Arc<V>>

Get from the cache. If the key is missing, do not generate it and return None

pub async fn drop(&self, key: &K)

Drop the key from the cache if it it exists

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

Get the key from cache. If not found, generate one.
