[0.9.1]

  • Bugfix: LruCache::contains_key should take &self and not move the entry as though it is accessed.
  • Add basic CursorMut API to HashMap (thanks @olebedev!)
  • Bump hashbrown dependency to depend on a version of hashbrown past a downstream zerocopy dependency.
  • Don't depend on default features of hashbrown, removes allocator-api2 dependency.

[0.9.0]

  • API incompatible change: Don't panic in reserve and try_reserve in cases where a rehash is needed. Previously would panic, adds the proper bounds on reserve methods to do a rehash (previously bounds were missing, and reserve would result in panics). (Thank you @cuviper!)

[0.8.4]

  • Now builds with #![no_std].

[0.8.3]

  • bump hashbrown to 0.14

[0.8.2]

  • bump hashbrown to 0.13

[0.8.1]

  • Add retain_with_order methods, equivalent to retain but which iterate through the map in the proper linked list order

[0.8.0]

  • API incompatible change: No longer re-export hashbrown types so that bumping hashbrown is no longer an API compatible change.
  • bump hashbrown to 0.12
  • Fix implementation of shrink_to_fit to not panic when called on non-empty containers.

[0.7.0]

  • API incompatible change: depend on hashbrown 0.11, changes re-exported types.
  • Fix LinkedHashSet::back to take &self not &mut self.
  • API incompatible change: equality tests on LinkedHashSet are now ordered, similar to LinkedHashMap.
  • Make the serde Deserialize implementations on LinkedHashMap and LinkedHashSet generic on the BuildHasher type.
  • Add to_back and to_front methods for LinkedHashMap to control entry order.

[0.6.0]

  • API incompatible change: depend on hashbrown 0.9, re-export renamed hashbrown::TryReserveError type.
  • Add a Debug impl to LruCache (thanks @thomcc!)
  • Adjust trait bounds for LinkedHashMap::retain, LinkedHashSet::default to be less strict (to match hashbrown)
  • Adjust trait bounds for all Debug impls to be less strict (to match hashbrown).
  • Adjust trait bounds for all IntoIterator impls to be less strict (to match hashbrown).
  • Adjust trait bounds for LruCache::with_hasher, LruCache::capacity, LruCache::len, LruCache::is_empty, LruCache::clear, LruCache::iter, LruCache::iter_mut, and LruCache::drain to be less strict
  • Add optional serde support for LinkedHashMap and LinkedHashSet.
  • Add to_back and to_front methods for LinkedHashSet to control entry order.

[0.5.1]

  • Add LinkedHashMap::remove_entry and LruCache::remove_entry
  • Add LruCache::new_unbounded constructor that sets capacity to usize::MAX
  • Add LruCache::get method to go with LruCache::get_mut
  • Add LruCache::peek and LruCache::peek_mut to access the cache without moving the entry in the LRU list

[0.5.0]

  • API incompatible change: depend on hashbrown 0.7

[0.4.0]

  • API incompatible change: depend on hashbrown 0.6
  • Passes miri

[0.3.0]

  • Add some minimal documentation for methods that change the internal ordering.
  • Decide on a pattern for methods that change the internal ordering: the word "insert" means that it will move an existing entry to the back.
  • Some methods have been renamed to conform to the above system.

[0.2.1]

  • Fix variance for LinkedHashMap (now covariant where appropriate)
  • Add Debug impls to many more associated types
  • Add LinkedHashSet
  • Add LinkedHashMap::retain

[0.2.0]

  • Move linked_hash_map into its own module
  • Add LruCache type ported from lru-cache crate into its own module
  • Add LruCache entry and raw-entry API
  • Add linked_hash_map IntoIter iterator that is different from Drain iterator
  • Make Drain iterator recycle freed linked list nodes

[0.1.0]

  • Initial release
