| description: | ||
| A newtype over 'Bool' with a better 'Vector' instance. | ||
| . | ||
| The [vector](https://hackage.haskell.org/package/vector) | ||
| package represents unboxed arrays of 'Bool' | ||
| This library provides a newtype wrapper 'Bit' and a custom instance | ||
| of unboxed 'Vector', which packs bits densely, | ||
| achieving __8x less memory footprint.__ | ||
| The performance stays mostly the same; | ||
| the most significant degradation happens for random writes | ||
| (up to 10% slower). | ||
| On the other hand, for certain bulk bit operations | ||
| 'Vector Bit' is up to 64x faster than 'Vector Bool'. | ||
| . | ||
| === Thread safety | ||
| . | ||
| * "Data.Bit" is faster, but writes and flips are thread-unsafe. | ||
| This is because naive updates are not atomic: | ||
| read the whole word from memory, | ||
| then modify a bit, then write the whole word back. | ||
| * "Data.Bit.ThreadSafe" is slower (up to 20%), | ||
| but writes and flips are thread-safe. | ||
| . | ||
| === Similar packages | ||
| . | ||
| * [bv](https://hackage.haskell.org/package/bv) and | ||
| [bv-little](https://hackage.haskell.org/package/bv-little) | ||
| do not offer mutable vectors. | ||
| . | ||
| * [array](https://hackage.haskell.org/package/array) | ||
| is memory-efficient for 'Bool', but lacks | ||
| a handy 'Vector' interface and is not thread-safe. | ||
