Release Notes

indexmap-rs/indexmap (indexmap)

v2.4.0

Compare Source

• Added methods IndexMap::append and IndexSet::append, moving all items from
  one map or set into another, and leaving the original capacity for reuse.

v2.3.0

Compare Source

• Added trait MutableEntryKey for opt-in mutable access to map entry keys.
• Added method MutableKeys::iter_mut2 for opt-in mutable iteration of map
  keys and values.

v2.2.6

Compare Source

• Added trait MutableValues for opt-in mutable access to set values.

v2.2.5

Compare Source

• Added optional borsh serialization support.

v2.2.4

Compare Source

• Added an insert_sorted method on IndexMap, IndexSet, and VacantEntry.
• Avoid hashing for lookups in single-entry maps.
• Limit preallocated memory in serde deserializers.

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.

v2.2.2

Compare Source

• Added indexing methods to raw entries: RawEntryBuilder::from_hash_full,
  RawEntryBuilder::index_from_hash, and RawEntryMut::index.

v2.2.1

Compare Source

• Corrected the signature of RawOccupiedEntryMut::into_key(self) -> &'a mut K,
  This a breaking change from 2.2.0, but that version was published for less
  than a day and has now been yanked.

v2.2.0

Compare Source

• The new IndexMap::get_index_entry method finds an entry by its index for
  in-place manipulation.

• The Keys iterator now implements Index<usize> for quick access to the
  entry's key, compared to indexing the map to get the value.

• The new IndexMap::splice and IndexSet::splice methods will drain the
  given range as an iterator, and then replace that range with entries from
  an input iterator.

• The new trait RawEntryApiV1 offers opt-in access to a raw entry API for
  IndexMap, corresponding to the unstable API on HashSet as of Rust 1.75.

• Many IndexMap and IndexSet methods have relaxed their type constraints,
  e.g. removing K: Hash on methods that don't actually need to hash.

• Removal methods remove, remove_entry, and take are now deprecated
  in favor of their shift_ or swap_ prefixed variants, which are more
  explicit about their effect on the index and order of remaining items.
  The deprecated methods will remain to guide drop-in replacements from
  HashMap and HashSet toward the prefixed methods.

v2.1.0

Compare Source

• Empty slices can now be created with map::Slice::{new, new_mut} and
  set::Slice::new. In addition, Slice::new, len, and is_empty are
  now const functions on both types.

• IndexMap, IndexSet, and their respective Slices all have binary
  search methods for sorted data: map binary_search_keys and set
  binary_search for plain comparison, binary_search_by for custom
  comparators, binary_search_by_key for key extraction, and
  partition_point for boolean conditions.

v2.0.2

Compare Source

• The hashbrown dependency has been updated to version 0.14.1 to
  complete the support for Rust 1.63.

v2.0.1

Compare Source

• MSRV: Rust 1.63.0 is now supported as well, pending publication of
  hashbrown's relaxed MSRV (or use cargo --ignore-rust-version).

v2.0.0

Compare Source

• MSRV: Rust 1.64.0 or later is now required.

• The "std" feature is no longer auto-detected. It is included in the
  default feature set, or else can be enabled like any other Cargo feature.

• The "serde-1" feature has been removed, leaving just the optional
  "serde" dependency to be enabled like a feature itself.

• IndexMap::get_index_mut now returns Option<(&K, &mut V)>, changing
  the key part from &mut K to &K. There is also a new alternative
  MutableKeys::get_index_mut2 to access the former behavior.

• The new map::Slice<K, V> and set::Slice<T> offer a linear view of maps
  and sets, behaving a lot like normal [(K, V)] and [T] slices. Notably,
  comparison traits like Eq only consider items in order, rather than hash
  lookups, and slices even implement Hash.

• IndexMap and IndexSet now have sort_by_cached_key and
  par_sort_by_cached_key methods which perform stable sorts in place
  using a key extraction function.

• IndexMap and IndexSet now have reserve_exact, try_reserve, and
  try_reserve_exact methods that correspond to the same methods on Vec.
  However, exactness only applies to the direct capacity for items, while the
  raw hash table still follows its own rules for capacity and load factor.

• The Equivalent trait is now re-exported from the equivalent crate,
  intended as a common base to allow types to work with multiple map types.

• The hashbrown dependency has been updated to version 0.14.

• The serde_seq module has been moved from the crate root to below the
  map module.

perhaps a crate was updated and forgotten to be re-vendored?
