[dependabot]

Updates the requirements on hashlink to permit the latest version.

Release notes

Sourced from hashlink's releases.

v0.9.1

• 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.

Changelog

Sourced from hashlink's changelog.

[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
