Changelog

Sourced from hashbrown's changelog.

0.15.4 - 2025-06-05

Changed

• Removed optional dependency on compiler-builtins. This only affects building as part of std.

0.15.3 - 2025-04-29

Added

• SIMD implementation for LoongArch (#592, requires nightly)

Changed

• Optimized insertion path by avoiding an unnecessary match_empty (#607)
• Increased minimum table size for small types (#615)
• Dropped FnMut trait bounds from ExtractIf data structures (#616)
• Relaxed constraint in hash_map::EntryRef insertion methods K: From<&Q> to &Q: Into<K> (#611)
• Added allocator template argument for rustc_iter (#605)
• The allocator-api2/nightly feature is no longer enabled by hashbrown/nightly (#606)

[v0.15.2] - 2024-11-14

Added

• Marked const fn constructors as rustc_const_stable_indirect when built as part of the standard library. (#586)

[v0.15.1] - 2024-11-03

This release removes the borsh feature introduced in 0.15.0 because it was found to be incorrectly implemented. Users should use the hashbrown feature of the borsh crate instead which provides the same trait implementations.

[v0.15.0] - 2024-10-01

This release was yanked due to a broken implementation of the borsh feature.

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)
