Trait Cache 

pub trait Cache<K, V>: Send + Sync {
    // Required methods
    fn get(&self, key: &K) -> Option<V>;
    fn put(&self, key: K, value: V, ttl_secs: u64);
    fn remove(&self, key: &K) -> Option<V>;
    fn clear(&self);
}

Cache trait for storing and retrieving values with TTL

Required Methods

fn get(&self, key: &K) -> Option<V>

Get a value from the cache

fn put(&self, key: K, value: V, ttl_secs: u64)

Put a value into the cache with TTL in seconds

fn remove(&self, key: &K) -> Option<V>

Remove a value from the cache

fn clear(&self)

Clear all values from the cache

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
