---
A simple fixed size bitset container for Rust.
Please read the [API documentation here](https://docs.rs/fixedbitset/)
[![build\_status](https://github.com/petgraph/fixedbitset/workflows/Continuous%20integration/badge.svg?branch=master)](https://github.com/petgraph/fixedbitset/actions)
[![crates](https://img.shields.io/crates/v/fixedbitset.svg)](https://crates.io/crates/fixedbitset)
# Recent Changes
- 0.5.7
- [#127](https://github.com/petgraph/fixedbitset/pull/127) and [#128](https://github.com/petgraph/fixedbitset/pull/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](https://github.com/petgraph/fixedbitset/pull/116): Add functions for counting the results of a set operation (`union_count`,
`intersection_count`, `difference_count`, `symmetric_difference_count`) by @james7132.
- [#118](https://github.com/petgraph/fixedbitset/pull/118): Shrink the stack size of FixedBitset. There should be zero stack size overhead
compared to a Vec.
- [#119](https://github.com/petgraph/fixedbitset/pull/119): Fix builds for wasm32.
- [#120](https://github.com/petgraph/fixedbitset/pull/119): 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](https://github.com/petgraph/fixedbitset/pull/121): Add support for SIMD acceleration for AVX builds.
- 0.5.4
- [#112](https://github.com/petgraph/fixedbitset/pull/112): Fix undefined behavior in IntoOnes and setup testing with MIRI by @SkiFire13
- 0.5.3 (yanked)
- [#109](https://github.com/petgraph/fixedbitset/pull/109): Fix non-x86(_64) builds by @james7132
- 0.5.2 (yanked)
- [#86](https://github.com/petgraph/fixedbitset/pull/86): Explicit SIMD vectorization for set operations by @james7132.
- 0.5.1
- [#102](https://github.com/petgraph/fixedbitset/pull/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](https://github.com/petgraph/fixedbitset/pull/103): Added `into_ones` which returns a owned iterator over the one
values from a bitset, by @james7132.
- [#104](https://github.com/petgraph/fixedbitset/pull/104): Implemented `DoubleEndedIterator` for `Union`, `Intersection`,
`Difference`, and `SymmetricDifference` , by @james7132.
- 0.5.0
- [#74](https://github.com/petgraph/fixedbitset/pull/74): Accelerated set operations (union, intersection, difference,
symmetric difference) by using larger blocks internally, by @james7132.
- [#88](https://github.com/petgraph/fixedbitset/pull/88): Added `FixedBitSet::remove` by @james7132.
- [#89](https://github.com/petgraph/fixedbitset/pull/89): Added `FixedBitSet::zeros` and the `Zeros` iterator by @james7132.
- [#92](https://github.com/petgraph/fixedbitset/pull/92): Added `FixedBitSet::grow_and_insert` function, a
non-panicking version of `insert` that grows the underlying storage as need, by @shuoli84.
- [#98](https://github.com/petgraph/fixedbitset/pull/98): `Ones` now implements `DoubleEndedIterator`, by @tikhu.
- [#99](https://github.com/petgraph/fixedbitset/pull/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](https://github.com/petgraph/fixedbitset/pull/79): Add `is_clear`,
clarify `is_empty` and `len` documentation by \@nicopap.
