fixedbitset --- 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. - 0.4.1 - Documentation and formatting fixes. - 0.4.0 - [#61](https://github.com/petgraph/fixedbitset/pull/61): Require Rust 1.39. - [#60](https://github.com/petgraph/fixedbitset/pull/60): Add `const` `FixedBitSet::new` consructor by \@jakobhellermann. - [#59](https://github.com/petgraph/fixedbitset/pull/59): Add optional `serde` support by \@keshavsn. - 0.3.2 - [#18](https://github.com/petgraph/fixedbitset/pull/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. - 0.1.3 - Add method `.put()` to enable a bit and return previous value - 0.1.2 - Add method `.copy_bit()` (by fuine) - impl Default - 0.1.1 - Update documentation URL - 0.1.0 - Add method `.grow()` # License Dual-licensed to be compatible with the Rust project.
