Crate sieve_cache
source ·Expand description
A cache based on the SIEVE eviction algorithm.
Usage
use sieve_cache::SieveCache;
// Create a new cache with a capacity of 100000.
let mut cache: SieveCache<String, String> = SieveCache::new(100000).unwrap();
// Insert key/value pairs into the cache.
cache.insert("foo".to_string(), "foocontent".to_string());
cache.insert("bar".to_string(), "barcontent".to_string());
// Remove an entry from the cache.
cache.remove("bar");
// Retrieve a value from the cache, returning `None` or a reference to the value.
assert_eq!(cache.get("foo"), Some(&"foocontent".to_string()));
// Check if a key is in the cache.
assert_eq!(cache.contains_key("bar"), false);
// Get a mutable reference to a value in the cache.
if let Some(value) = cache.get_mut("foo") {
*value = "newfoocontent".to_string();
}
// Return the number of cached values.
assert_eq!(cache.len(), 1);
// Return the capacity of the cache.
assert_eq!(cache.capacity(), 100000);
