Struct sp_std::iter::Scan1.0.0[][src]

#[must_use = "iterators are lazy and do nothing unless consumed"]pub struct Scan<I, St, F> { /* fields omitted */ }

An iterator to maintain state while iterating another iterator.

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