Struct PrefixMatcher 

pub struct PrefixMatcher { /* private fields */ }

String prefix matcher for finding keys that start with a specific string.

This matcher is useful for finding groups of related cache entries that follow a naming convention with common prefixes.

Examples

use simple_cacher::*;
use std::time::Duration;

let mut cache = SimpleCacher::new(Duration::from_secs(300));
cache.insert("user:alice".to_string(), "Alice Johnson".to_string());
cache.insert("user:bob".to_string(), "Bob Smith".to_string());
cache.insert("admin:charlie".to_string(), "Charlie Admin".to_string());

let user_matcher = PrefixMatcher::new("user:");
let users = cache.get_all_by_matcher(&user_matcher);
assert_eq!(users.len(), 2); // Found alice and bob
