34/// Type alias for HashSet to provide a stable API abstraction over the underlying hash set implementation.
35///
36/// This alias allows the library to use a high-performance hash set implementation
37/// (currently hashbrown::HashSet) while providing API stability to users. It also
38/// ensures consistent usage across the entire codebase.
39///
40/// # Examples
41///
42/// ```ignore
43/// use mqtt_protocol_core::mqtt::common::HashSet;
44///
45/// let mut set = HashSet::new();
46/// set.insert("key");
