Type Alias HashData 

pub type HashData = KevyMap<SmallBytes, Vec<u8>>;

Backing structure for a Hash value — KevyMap keyed by SmallBytes (22 B inline / heap-else). Field names ≤22B (the vast majority — name, email, etc.) live entirely inside the bucket, saving the 24 B Vec metadata + heap allocation per field on a 22-byte budget.

Aliased Type

pub struct HashData { /* private fields */ }
