Struct CacheDriver 

pub struct CacheDriver<K, V, L>
where
    K: Clone + Eq + Hash + Ord + Debug + Send + 'static,
    V: Clone + Debug + Send + 'static,
    L: CacheLoader<K = K, V = V>,
{ /* private fields */ }

Combine a CacheBackend and a [Loader] into a single [Cache]

Implementations

impl<K, V, L> CacheDriver<K, V, L>

where K: Clone + Eq + Hash + Ord + Debug + Send + 'static, V: Clone + Debug + Send + 'static, L: CacheLoader<K = K, V = V>,

pub fn new(backend: CacheBackend<K, V>, loader: Arc<L>) -> Self

Create new, empty cache with given loader function.

Trait Implementations

impl<K, V, L> Debug for CacheDriver<K, V, L>

where K: Clone + Eq + Hash + Ord + Debug + Send + 'static + Debug, V: Clone + Debug + Send + 'static + Debug, L: CacheLoader<K = K, V = V> + Debug,

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

Formats the value using the given formatter.

impl<K, V, L> Drop for CacheDriver<K, V, L>

where K: Clone + Eq + Hash + Ord + Debug + Send + 'static, V: Clone + Debug + Send + 'static, L: CacheLoader<K = K, V = V>,

fn drop(&mut self)

Executes the destructor for this type.

impl<K, V, L> LoadingCache for CacheDriver<K, V, L>

where K: Clone + Eq + Hash + Ord + Debug + Send + 'static, V: Clone + Debug + Send + 'static, L: CacheLoader<K = K, V = V>,

type K = K

Cache key.

type V = V

Cache value.

type GetExtra = <L as CacheLoader>::Extra

Extra data that is provided during GET but that is NOT part of the cache key.

fn get_if_present(&self, k: Self::K) -> Option<Self::V>

Get value from cache.

fn get_with_status<'life0, 'async_trait>( &'life0 self, k: Self::K, extra: Self::GetExtra, ) -> Pin<Box<dyn Future<Output = (Self::V, CacheGetStatus)> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get value from cache and the status.

fn put<'life0, 'async_trait>( &'life0 self, k: Self::K, v: Self::V, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Side-load an entry into the cache. If the cache previously contained a value associated with key, the old value is replaced by value.

fn invalidate(&self, k: Self::K)

Discard any cached value for the key.

fn get<'life0, 'async_trait>( &'life0 self, k: Self::K, extra: Self::GetExtra, ) -> Pin<Box<dyn Future<Output = Self::V> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Get value from cache.
