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.
