Release Notes

v2.2.3

Compare Source

• Added move_index and swap_indices methods to IndexedEntry,
  OccupiedEntry, and RawOccupiedEntryMut, functioning like the existing
  methods on IndexMap.
• Added shift_insert methods on VacantEntry and RawVacantEntryMut, as
  well as shift_insert_hashed_nocheck on the latter, to insert the new entry
  at a particular index.
• Added shift_insert methods on IndexMap and IndexSet to insert a new
  entry at a particular index, or else move an existing entry there.
