Struct std::iter::MapWhile

#[must_use = "iterators are lazy and do nothing unless consumed"]pub struct MapWhile<I, P> { /* fields omitted */ }
🔬 This is a nightly-only experimental API. (iter_map_while #68537)recently added

An iterator that only accepts elements while predicate returns Some(_).

This struct is created by the map_while method on Iterator. See its documentation for more.
