Description

Effects: Applies f to the elements of [first, last) in order while f returns true. Equivalent to: while(first != last && f(*first)) ++first; return {first, std::move(f)};

Requires: decltype(first) is the iterator or const_iterator of an instantiation of hub and [first, last) is a valid range.

Returns: A pair with the iterator past the last visited element and std::move(f).

Note: Potentially faster than the equivalent loop thanks to internal unrolling and prefetching.
