Struct Items 

pub struct Items<T>(/* private fields */);

An eager Sequence wrapper around an iterator’s collected items.

A lazy iterator cannot implement Sequence directly: the trait borrows its items through &self, and a blanket impl<I: Iterator> would collide with the concrete collection impls under coherence. Items sidesteps both problems by collecting the iterator into a Vec<T> up front, which means the assertion sees a full, indexable view of the produced values.

Construct one with items. The wrapper is just a Vec<T> underneath, so it carries no surprises around iteration order or repeated reads.
