Recent Changes

• 0.5.7
  • #127 and #128: Optimize Clone::clone_from to avoid extra allocations and copies.
• 0.5.6
  • Fixed FixedBitset not implementing Send/Sync due to the stack size shrink.
• 0.5.5 (yanked)
  • #116: Add functions for counting the results of a set operation (union_count, intersection_count, difference_count, symmetric_difference_count) by @james7132.
  • #118: Shrink the stack size of FixedBitset. There should be zero stack size overhead compared to a Vec.
  • #119: Fix builds for wasm32.
  • #120: Add more utility functions that were previously missing from the public interface: contains_any_in_range, contains_all_in_range, minimum, maximum, is_full, count_zeroes, and remove_range.
  • #121: Add support for SIMD acceleration for AVX builds.
• 0.5.4
  • #112: Fix undefined behavior in IntoOnes and setup testing with MIRI by @SkiFire13
• 0.5.3 (yanked)
  • #109: Fix non-x86(_64) builds by @james7132
• 0.5.2 (yanked)
  • #86: Explicit SIMD vectorization for set operations by @james7132.
• 0.5.1
  • #102: Added contains_unchecked, insert_unchecked, put_unchecked, set_unchecked, toggle_unchecked, removed_unchecked, copy_bit_unchecked unsafe variants of the safe functions, by @james7132
  • #103: Added into_ones which returns a owned iterator over the one values from a bitset, by @james7132.
  • #104: Implemented DoubleEndedIterator for Union, Intersection, Difference, and SymmetricDifference , by @james7132.
• 0.5.0
  • #74: Accelerated set operations (union, intersection, difference, symmetric difference) by using larger blocks internally, by @james7132.
  • #88: Added FixedBitSet::remove by @james7132.
  • #89: Added FixedBitSet::zeros and the Zeros iterator by @james7132.
  • #92: Added FixedBitSet::grow_and_insert function, a non-panicking version of insert that grows the underlying storage as need, by @shuoli84.
  • #98: Ones now implements DoubleEndedIterator, by @tikhu.
  • #99: Breaking change: serde now serializes and deserializes from a little-endian encoded raw byte buffer. Existing stored instances of the serialized bitsets will need to be re-encoded.
  • Bumped MSRV to 1.56.
• 0.4.2
  • #79: Add is_clear, clarify is_empty and len documentation by @nicopap.
• 0.4.1
  • Documentation and formatting fixes.
• 0.4.0
  • #61: Require Rust 1.39.
  • #60: Add const FixedBitSet::new consructor by @jakobhellermann.
  • #59: Add optional serde support by @keshavsn.
• 0.3.2
  • #18: Optimize ones using trailing_zeroes by @vks
• 0.3.1
  • Add bit assign operators for references by @flaghacker
  • Improve assertion error messages by @lovasoa
  • Add documentation examples for with_capacity_and_blocks
• 0.3.0
  • Add with_capacity_and_blocks by @luizirber
  • Add difference_with by @sunshowers
  • Implement Binary and Display traits by @Dolphindalt
  • Add toggle_range by @wirelyre
• 0.2.0
  • Add assign operators for the bit operations by @jrraymond
  • Add symmetric_difference, union_with, intersection_with by @jrraymond
  • Add is_subset, is_superset, is_disjoint by @nwn
  • Add .toggle(i) method by @ShiroUsagi-san
  • Add default feature "std" which can be disabled to make the crate not link the std library. By @jonimake and @bluss
  • Require Rust 1.31.
• 0.1.9
  • Add intersection, union, difference iterators by @jrraymond
  • Add intersection: & and union: | operator implementations by @jrraymond
  • Add Extend and FromIterator implementations (from sequences of bit indices) by @jrraymond
• 0.1.8
  • Add missing #[inline] on the ones iterator
  • Fix docs for insert_range, set_range
• 0.1.7
  • Add fast methods .insert_range, .set_range by @kennytm
• 0.1.6
  • Add iterator .ones() by @mneumann
  • Fix bug with .count_ones() where it would erronously have an out-of-bounds panic for even block endpoints
• 0.1.5
  • Add method .count_ones(range).
• 0.1.4
  • Remove an assertion in .copy_bit(from, to) so that it is in line with the documentation. The from bit does not need to be in bounds.
  • Improve .grow() to use Vec::resize internally.
