Struct KeyValueRef 

pub struct KeyValueRef<'a, Key, Value>
where
    Key: Eq + Hash,
{ /* private fields */ }

KeyValueRef contains DashMap’s Ref dashmap::mapref::one::Ref which internally holds a RwLockReadGuard for the shard. It is returned as a response to get_ref method of crate::cache::cached::CacheD.

Any time get_ref method is invoked, the Store returns Option<KeyValueRef<'_, Key, StoredValue<Value>>>.

If the key is present in the Store, get_ref will return Some<KeyValueRef<'_, Key, StoredValue<Value>>>.

Hence, the invocation of get_ref will hold a lock against the shard that contains the key (within the scope of its usage).

Implementations

impl<'a, Key, Value> KeyValueRef<'a, Key, Value>

where Key: Eq + Hash,

pub fn key(&self) -> &Key

Returns the reference of the key present in the Store

pub fn value(&self) -> &Value

Returns the reference of the value present in the Store
