Changelog

Sourced from indexmap's changelog.

• 1.9.0

  • MSRV: Rust 1.56.1 or later is now required.

  • The hashbrown dependency has been updated to version 0.12.

  • IterMut and ValuesMut now implement Debug.

  • The new IndexMap::shrink_to and IndexSet::shrink_to methods shrink the capacity with a lower bound.

  • The new IndexMap::move_index and IndexSet::move_index methods change the position of an item from one index to another, shifting the items between to accommodate the move.

• 1.8.2

  • Bump the rustc-rayon dependency, for compiler use only.

• 1.8.1

  • The new IndexSet::replace_full will return the index of the item along with the replaced value, if any, by @​zakcutner in PR 222.

• 1.8.0

  • The new IndexMap::into_keys and IndexMap::into_values will consume the map into keys or values, respectively, matching Rust 1.54's HashMap methods, by @​taiki-e in PR 195.

  • More of the iterator types implement Debug, ExactSizeIterator, and FusedIterator, by @​cuviper in PR [196].

  • IndexMap and IndexSet now implement rayon's ParallelDrainRange, by @​cuviper in PR [197].

  • IndexMap and IndexSet now implement From for arrays, matching Rust 1.56's implementation for HashMap, by @​rouge8 in PR [205].

  • IndexMap and IndexSet now have methods sort_unstable_keys, sort_unstable_by, sorted_unstable_by, and par_* equivalents, which sort in-place without preserving the order of equal items, by @​bhgomes in PR [211].
