Release Notes

rust-lang/hashbrown (hashbrown)

v0.15.0

Compare Source

This update contains breaking changes that remove the raw API with the hope of
centralising on the HashTable API in the future. You can follow the discussion
and progress in #​545 to discuss features you think should be added to this API
that were previously only possible on the raw API.

Added

• Added borsh feature with BorshSerialize and BorshDeserialize impls. (#​525)
• Added Assign impls for HashSet operators. (#​529)
• Added Default impls for iterator types. (#​542)
• Added HashTable::iter_hash{,_mut} methods. (#​549)
• Added Hash{Table,Map,Set}::allocation_size methods. (#​553)
• Implemented Debug and FusedIterator for all HashTable iterators. (#​561)
• Specialized Iterator::fold for all HashTable iterators. (#​561)

Changed

• Changed hash_set::VacantEntry::insert to return OccupiedEntry. (#​495)
• Improvedhash_set::Difference::size_hint lower-bound. (#​530)
• Improved HashSet::is_disjoint performance. (#​531)
• equivalent feature is now enabled by default. (#​532)
• HashSet operators now return a set with the same allocator. (#​529)
• Changed the default hasher to foldhash. (#​563)
• ahash feature has been renamed to default-hasher. (#​533)
• Entry API has been reworked and several methods have been renamed. (#​535)
• Hash{Map,Set}::insert_unique_unchecked is now unsafe. (#​556)
• The signature of get_many_mut and related methods was changed. (#​562)

Fixed

• Fixed typos, stray backticks in docs. (#​558, #​560)

Removed

• Raw entry API is now under raw-entry feature, to be eventually removed. (#​534, #​555)
• Raw table API has been made private and the raw feature is removed;
  in the future, all code should be using the HashTable API instead. (#​531, #​546)
• rykv feature was removed; this is now provided by the rykv crate instead. (#​554)
• HashSet::get_or_insert_owned was removed in favor of get_or_insert_with. (#​555)
