Struct StoredValue 

pub struct StoredValue<Value> { /* private fields */ }

StoredValue wraps the client provided Value and it is stored as a value in the crate::cache::store::Store.

It encapsulates the value, key_id, the optional expiry of the key. and a flag to identify whether a key is soft deleted

It is relevant to the clients on the invocation of get_ref and map_get_ref methods on crate::cache::cached::CacheD.

use tinylfu_cached::cache::cached::CacheD;
use tinylfu_cached::cache::command::CommandStatus;
use tinylfu_cached::cache::config::ConfigBuilder;
#[tokio::main]
 async fn main() {
    let cached = CacheD::new(ConfigBuilder::new(100, 10, 100).build());
    let status = cached.put("topic", "microservices").unwrap().handle().await;
    assert_eq!(CommandStatus::Accepted, status);
    let value = cached.get_ref(&"topic");
    let value_ref = value.unwrap();
    let stored_value = value_ref.value();
    assert_eq!("microservices", stored_value.value());
}

Implementations

impl<Value> StoredValue<Value>

pub fn value_ref(&self) -> &Value

Returns a reference to the value stored inside Store

pub fn key_id(&self) -> u64

pub fn expire_after(&self) -> Option<SystemTime>

Returns the expiry of the key. It returns: None: if the expiry is not set Some: if the expiry is set

impl<Value> StoredValue<Value>

where Value: Clone,

pub fn value(&self) -> Value

Returns the cloned value stored inside Store
