Trait former::exposed::HashSetLike

pub trait HashSetLike<E>
where
    E: Eq + Hash,
{
    // Required method
    fn insert(&mut self, element: E) -> Option<E>;
}

A trait for containers behaving like a HashSet, allowing insertion operations.

Implementing this trait enables the associated formed to be used with HashSetSubformer, facilitating a builder pattern that is both intuitive and concise.
