Struct ContainsMatcher 

pub struct ContainsMatcher { /* private fields */ }

String substring matcher for finding keys that contain a specific string.

This matcher searches for cache entries where the key contains the specified substring anywhere within it.

Examples

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

let mut cache = SimpleCacher::new(Duration::from_secs(300));
cache.insert("user_profile_123".to_string(), "Profile data".to_string());
cache.insert("user_settings_456".to_string(), "Settings data".to_string());
cache.insert("admin_config".to_string(), "Config data".to_string());

let profile_matcher = ContainsMatcher::new("profile");
let profiles = cache.get_all_by_matcher(&profile_matcher);
assert_eq!(profiles.len(), 1);
