Function differential_dataflow::consolidation::consolidate_from

pub fn consolidate_from<T: Ord, R: Semigroup>(
    vec: &mut Vec<(T, R)>, 
    offset: usize
)

Sorts and consolidate vec[offset..].

This method will sort vec[offset..] and then consolidate runs with the same first element of a pair by accumulating the second elements of the pairs. Should the final accumulation be zero, the element is discarded.
