Description :
A newtype over \'Bool\' with a better \'Vector\' instance: 8x less memory, up to
1000x faster.
The < https://hackage.haskell.org/package/vector vector> package represents
unboxed arrays of \'Bool\'s spending 1 byte (8 bits) per boolean. This library
provides a newtype wrapper \'Bit\' and a custom instance of an unboxed \'Vector\',
which packs bits densely, achieving an __8x smaller 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 1000x 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: they 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
* < https://hackage.haskell.org/package/bv bv> and
< https://hackage.haskell.org/package/bv-little bv-little> do not offer mutable
vectors.
* < https://hackage.haskell.org/package/array array> is memory-efficient for
\'Bool\', but lacks a handy \'Vector\' interface and is not thread-safe.
