BitMagic Library

The RAW arbitrary size Bit-Vector implementation in JavaScript

Bitset data structure

Bit vectors: 8x less memory, up to 3500x faster than Vector Bool

C API for creation and analysis of binary data

A Go package providing data types and functions for manipurating bit arrays, aka bit strings, of arbitrary length.

A bit-array manipulation library in C

High-performance C# Data Structures library (Grid2D, BitArray, RingBuffer, EnumSet) optimized for memory and CPU cache locality. Available on NuGet & OpenUPM.

Efficient numerics for bit-space a.k.a GF(2): The C++ version.

A Bitmap library (think BitArray, BitVector32, or Bit Index, not bmp) written in C# with more functionality than the .NET default.

Static bit-vector with primitive byte storage and bit-wise index

The optimal solution to the problem of counting unique IPv4 addresses in a huge text file.

Efficient numerics for bit-space a.k.a GF(2): The Rust version.

FSK algorithm for Assignment with one sound application

Back end array, declared as ordinary byte array (8-bits). But internal datastructure managed as a 'collection' of bit-subarrays:

Set of classes implementing bit vector (an array of individually accessible bits).

A Swift package for bit vectors (also called bit arrays).

Byte and Word conversions (hex, char, bitstring)

Experimental code to investigate various methods of providing a simple, direct access bit array in PHP, able to handle many (tens of millions of) boolean value elements. We compare several methods available in standard PHP and a custom PHP extension to provide faster, more memory efficient storage.
