- 1.3.2
- Maintenance update to regenerate the published `Cargo.toml`.
- 1.3.1
- Maintenance update for formatting and ``autocfg`` 1.0.
- 1.3.0
- The deprecation messages in the previous version have been removed.
(The methods have not otherwise changed.) Docs for removal methods have been
improved.
- From Rust 1.36, this crate supports being built **without std**, requiring
``alloc`` instead. This is enabled automatically when it is detected that
``std`` is not available. There is no crate feature to enable/disable to
trigger this. The new build-dep ``autocfg`` enables this.
- 1.2.0
- Plain ``.remove()`` now has a deprecation message, it informs the user
about picking one of the removal functions ``swap_remove`` and ``shift_remove``
which have different performance and order semantics.
Plain ``.remove()`` will not be removed, the warning message and method
will remain until further.
- Add new method ``shift_remove`` for order preserving removal on the map,
and ``shift_take`` for the corresponding operation on the set.
- Add methods ``swap_remove``, ``swap_remove_entry`` to ``Entry``.
- Fix indexset/indexmap to support full paths, like ``indexmap::indexmap!()``
- Internal improvements: fix warnings, deprecations and style lints
- 1.1.0
- Added optional feature `"rayon"` that adds parallel iterator support
to `IndexMap` and `IndexSet` using Rayon. This includes all the regular
iterators in parallel versions, and parallel sort.
- Implemented ``Clone`` for ``map::{Iter, Keys, Values}`` and
``set::{Difference, Intersection, Iter, SymmetricDifference, Union}``
- Implemented ``Debug`` for ``map::{Entry, IntoIter, Iter, Keys, Values}`` and
``set::{Difference, Intersection, IntoIter, Iter, SymmetricDifference, Union}``
- Serde trait ``IntoDeserializer`` are implemented for ``IndexMap`` and ``IndexSet``.
- Minimum Rust version requirement increased to Rust 1.30 for development builds.
- 1.0.2
- The new methods ``IndexMap::insert_full`` and ``IndexSet::insert_full`` are
both like ``insert`` with the index included in the return value.
- The new method ``Entry::and_modify`` can be used to modify occupied
entries, matching the new methods of ``std`` maps in Rust 1.26.
- The new method ``Entry::or_default`` inserts a default value in unoccupied
entries, matching the new methods of ``std`` maps in Rust 1.28.
- 1.0.1
- Document Rust version policy for the crate (see rustdoc)
- 1.0.0
- This is the 1.0 release for ``indexmap``! (the crate and datastructure
formerly known as “ordermap”)
- ``OccupiedEntry::insert`` changed its signature, to use ``&mut self`` for
the method receiver, matching the equivalent method for a standard
``HashMap``. Thanks to @dtolnay for finding this bug.
- The deprecated old names from ordermap were removed: ``OrderMap``,
``OrderSet``, ``ordermap!{}``, ``orderset!{}``. Use the new ``IndexMap``
etc names instead.
- 0.4.1
- Renamed crate to ``indexmap``; the ``ordermap`` crate is now deprecated
and the types ``OrderMap/Set`` now have a deprecation notice.
- 0.4.0
- This is the last release series for this ``ordermap`` under that name,
because the crate is **going to be renamed** to ``indexmap`` (with types
``IndexMap``, ``IndexSet``) and no change in functionality!
- The map and its associated structs moved into the ``map`` submodule of the
crate, so that the map and set are symmetric
+ The iterators, ``Entry`` and other structs are now under ``ordermap::map::``
- Internally refactored ``OrderMap<K, V, S>`` so that all the main algorithms
(insertion, lookup, removal etc) that don't use the ``S`` parameter (the
hasher) are compiled without depending on ``S``, which reduces generics bloat.
- ``Entry<K, V>`` no longer has a type parameter ``S``, which is just like
the standard ``HashMap``'s entry.
- Minimum Rust version requirement increased to Rust 1.18
- 0.3.5
- Documentation improvements
- 0.3.4
- The ``.retain()`` methods for ``OrderMap`` and ``OrderSet`` now
traverse the elements in order, and the retained elements **keep their order**
- Added new methods ``.sort_by()``, ``.sort_keys()`` to ``OrderMap`` and
``.sort_by()``, ``.sort()`` to ``OrderSet``. These methods allow you to
sort the maps in place efficiently.
- 0.3.3
- Document insertion behaviour better by @lucab
- Updated dependences (no feature changes) by @ignatenkobrain
- 0.3.2
- Add ``OrderSet`` by @cuviper!
- ``OrderMap::drain`` is now (too) a double ended iterator.
- 0.3.1
- In all ordermap iterators, forward the ``collect`` method to the underlying
iterator as well.
- Add crates.io categories.
- 0.3.0
- The methods ``get_pair``, ``get_pair_index`` were both replaced by
``get_full`` (and the same for the mutable case).
- Method ``swap_remove_pair`` replaced by ``swap_remove_full``.
- Add trait ``MutableKeys`` for opt-in mutable key access. Mutable key access
is only possible through the methods of this extension trait.
- Add new trait ``Equivalent`` for key equivalence. This extends the
``Borrow`` trait mechanism for ``OrderMap::get`` in a backwards compatible
way, just some minor type inference related issues may become apparent.
See `#10`__ for more information.
- Implement ``Extend<(&K, &V)>`` by @xfix.

- Improved performance of ``.insert()`` (`#3`__) by @pczarn.
__ https://github.com/bluss/ordermap/pull/3
- 0.2.3
- Generalize ``Entry`` for now, so that it works on hashmaps with non-default
hasher. However, there's a lingering compat issue since libstd ``HashMap``
does not parameterize its entries by the hasher (``S`` typarm).
- Special case some iterator methods like ``.nth()``.
- 0.2.2
- Disable the verbose ``Debug`` impl by default.
- 0.2.1
- Fix doc links and clarify docs.
- 0.2.0
- Add more ``HashMap`` methods & compat with its API.
- Experimental support for ``.entry()`` (the simplest parts of the API).
- Add ``.reserve()`` (placeholder impl).
- Add ``.remove()`` as synonym for ``.swap_remove()``.
- Changed ``.insert()`` to swap value if the entry already exists, and
return ``Option``.
- Experimental support as an *indexed* hash map! Added methods
``.get_index()``, ``.get_index_mut()``, ``.swap_remove_index()``,
``.get_pair_index()``, ``.get_pair_index_mut()``.
- 0.1.2
- Implement the 32/32 split idea for ``Pos`` which improves cache utilization
and lookup performance.
- 0.1.1
- Initial release.
