Module cache 

Cache policy for caching successful results.

The cache policy stores successful results and returns them for subsequent calls, reducing load on underlying services.

Examples

use do_over::{policy::Policy, cache::Cache, error::DoOverError};
use std::time::Duration;

// Cache results for 60 seconds
let policy = Cache::<String>::new(Duration::from_secs(60));

// First call executes the operation
let result: Result<String, DoOverError<String>> = policy.execute(|| async {
    Ok("expensive_result".to_string())
}).await;

// Subsequent calls return cached value (until TTL expires)
