Struct DashmapCache

pub struct DashmapCache { /* private fields */ }

Implementations

impl<'a> DashmapCache

pub fn new() -> Self

pub fn refresh_cache<F, A, V>( &self, invalidate_keys: &Vec<String>, closure: F, arg: A, ) -> Result<V, CacheError>

where F: Fn(&A) -> V, A: Hash + Sync + Send + Eq + Serialize, V: Send + Sync + Clone + Serialize + for<'b> Deserialize<'b>,

Atomic operation to replace a cached entry by a new computation value

pub fn cached<F, A, V>( &self, invalidate_keys: &Vec<String>, closure: F, arg: A, ) -> Result<V, CacheError>

where F: Fn(&A) -> V, A: Hash + Sync + Send + Eq + Serialize, V: Send + Sync + Clone + Serialize + for<'b> Deserialize<'b>,

Computes a signature for arg If already present in the cache, returns directly associated return value Otherwise, compute a new return value and fills the cache with it It is recommended to use a call enum and dispatch in the same closure for the same cache if the input types or values are susceptible to overlap.

pub async fn async_cached<F, A, V>( &self, invalidate_keys: &Vec<String>, closure: F, arg: A, ) -> Result<V, CacheError>

where F: Fn(&A) -> Pin<Box<dyn Future<Output = V>>>, A: Hash + Sync + Send + Eq + Serialize, V: Send + Sync + Clone + Serialize + for<'b> Deserialize<'b>,

Async version of cached()

pub fn invalidate(&self, tag: &str)
