Function competitive_hpp::prelude::merge_join_by

pub fn merge_join_by<I, J, F>(
    left: I, 
    right: J, 
    cmp_fn: F
) -> MergeJoinBy<<I as IntoIterator>::IntoIter, <J as IntoIterator>::IntoIter, F> where
    F: FnMut(&<I as IntoIterator>::Item, &<J as IntoIterator>::Item) -> Ordering,
    I: IntoIterator,
    J: IntoIterator, 

Return an iterator adaptor that merge-joins items from the two base iterators in ascending order.
