Boolean operations lifted to bitwise operations.
Lift a unary boolean operation to a bitwise operation.
The implementation is by exhaustive input/output case analysis: thus the operation provided must be total.
Lift a binary boolean operation to a bitwise operation.
The implementation is by exhaustive input/output case analysis: thus the operation provided must be total.
True when the predicate is true for any bit.
True when the predicate is true for all bits.
isUniform :: (Num b, Bits b) => b -> Maybe Bool Source
Determine if a Bits
is all 1s, all 0s, or neither.
Splitting/joining Bits
to/from (lsb, msb).
Split a word into (lsb, msb). Ensures lsb has no set bits above the split point.
Join lsb with msb to make a word. Assumes lsb has no set bits above the join point.
(Un)packing Bits
to/from lists of Bool
.
Convert a little-endian list of bits to Bits
.
Convert a big-endian list of bits to Bits
.
(Un)packing Word8
to/from 8-tuples of Bool
.
:: Bool | least significant bit |

Pack bits into a byte in little-endian order.
:: Word8 | |
-> (Bool, Bool, Bool, Bool, Bool, Bool, Bool, Bool) | (least significant bit, ..., most significant bit) |
Extract the bits from a byte in little-endian order.
