Enum Order 

pub enum Order {
    Asc,
    Desc,
}

Enum for specifying sort order when listing cache entries.

Examples

use quickleaf::Order;
use quickleaf::Cache;
use quickleaf::ListProps;
use quickleaf::valu3::traits::ToValueBehavior;

let mut cache = Cache::new(10);
cache.insert("zebra", 1);
cache.insert("apple", 2);
cache.insert("monkey", 3);

// Ascending order (default)
let props = ListProps::default().order(Order::Asc);
let results = cache.list(props).unwrap();
let keys: Vec<_> = results.iter().map(|(k, _)| k.as_str()).collect();
assert_eq!(keys, vec!["apple", "monkey", "zebra"]);

// Descending order
let props = ListProps::default().order(Order::Desc);
let results = cache.list(props).unwrap();
let keys: Vec<_> = results.iter().map(|(k, _)| k.as_str()).collect();
assert_eq!(keys, vec!["zebra", "monkey", "apple"]);

Variants

Asc

Sort keys in ascending order (A-Z).

Desc

Sort keys in descending order (Z-A).
