sorted_vector_map
is an implementation of an ordered map and set (like
std::collections::BTreeMap
and std::collections::BTreeSet
) using a sorted
vector as the backing store.
Sorted vector maps are appropriate when data is frequently loaded from an ordered source, queried a small number of times, and infrequently modified through insertion or removal.
Loading from an ordered sequence is O(n) through an optimization to insert
that handles in-order insertions specially. Extension of the sequence is also
optimized, where extending a map or set of size n with m elements in a single
operation is O(n + m log m). Otherwise, loading from an unordered sequence is
O(n^2).
Look-up is O(log n) through binary search. Insertion and removal are both O(n), as are set operations like intersection, union and difference.
