synopsis: Space-efficient bit vectors
description:
A newtype over 'Bool' with a better 'Vector' instance: 8x less memory, up to 3500x 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 3500x faster than 'Vector' 'Bool'.
.
=== Thread safety
.
* "Data.Bit" is faster, but writes and flips are not thread-safe.
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.
Concurrently modifying non-intersecting slices of the same underlying array
may also lead to unexpected results, since they can share a word in memory.
* "Data.Bit.ThreadSafe" is slower (usually 10-20%),
but writes and flips are thread-safe.
Additionally, concurrently modifying non-intersecting slices of the same underlying array
works as expected. However, operations that affect multiple elements are not
guaranteed to be atomic.
.
=== 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.
