Crate fixedbitset

FixedBitSet is a simple fixed size set of bits.

Crate features

• std (default feature)
  Disabling this feature disables using std and instead uses crate alloc.

SIMD Acceleration

fixedbitset is written with SIMD in mind. The backing store and set operations will use aligned SIMD data types and instructions when compiling for compatible target platforms. The use of SIMD generally enables better performance in many set and batch operations (i.e. intersection/union/inserting a range).

When SIMD is not available on the target, the crate will gracefully fallback to a default implementation. It is intended to add support for other SIMD architectures once they appear in stable Rust.

Currently only SSE2/AVX/AVX2 on x86/x86_64 and wasm32 SIMD are supported as this is what stable Rust supports.

Structs

• Difference
  An iterator producing elements in the difference of two sets.
• FixedBitSet
  FixedBitSet is a simple fixed size set of bits that each can be enabled (1 / true) or disabled (0 / false).
• Intersection
  An iterator producing elements in the intersection of two sets.
• IntoOnes
• Ones
  An iterator producing the indices of the set bit in a set.
• SymmetricDifference
  An iterator producing elements in the symmetric difference of two sets.
• Union
  An iterator producing elements in the union of two sets.
• Zeroes
  An iterator producing the indices of the set bit in a set.

Traits

• IndexRange
  IndexRange is implemented by Rust’s built-in range types, produced by range syntax like .., a.., ..b or c..d.
