BitCollections is a library that provides efficient collections storing bit values. It provides two types:

  • BitSet: An immutable struct, allocation-free when small bit indices are stored.

  • BitArrayNeo: A mutable class, has a similar API with System.Collections.BitArray, its modification methods return whether the collection changed.

These two types can be converted and checked for equality against each other. Both implement IEnumerable<int>, returning the indices of their active bits.

Missing features

BitArrayNeo is not a drop-in replacement for BitArray. In particular, it is missing features like:

  • The LeftShift/RightShift methods
  • Some additional constructors (such as accepting an array of bytes or booleans)
  • SIMD acceleration

BitSet is missing some set-relational operators (such as IsSubsetOf) that might come in handy. They will be added in a future release.
