Trait pattern_3::haystack::SharedHaystack

pub trait SharedHaystack: Haystack + Clonewhere
    Self::Target: Hay,{ }

A Haystack which can be shared and cheaply cloned (e.g. &H, Rc<H>).

If a haystack implements this marker trait, during internal operations the original haystack will be retained in full and cloned, rather than being sliced and splitted. Being a shared haystack allows searcher to see the entire haystack, including the consumed portion.
