First time here? We recommend starting with the Getting started guide, or reading through the example Hegel code below.

• Go
• C++
• TypeScript
• Java

use hegel::generators as gs;

use hegel::TestCase;

#[hegel::test]

fn test_respects_lru_capacity(tc: TestCase) {

    let capacity = tc.draw(gs::integers::<usize>().min_value(0));

    let mut cache = MyLRUCache::<String, i64>::new(capacity);

    let entries = tc.draw(

        gs::vecs(gs::tuples!(gs::text(), gs::integers::<i64>()))

    );

    for (key, value) in entries {

        cache.put(key, value);

    }

    assert!(cache.size() <= capacity);

}
