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.
Splitting/joining Bits
to/from (lsb, msb).
A mask with count least significant bits set.
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 Bits
to a list of bits, in
little-endian order.
Convert a big-endian list of bits to Bits
.
Arguments
:: FiniteBits b | |
=> b | |
-> [Bool] | \[most significant bit, ..., least significant bit\] |
Convert a FiniteBits
to a list of bits, in
big-endian order.
(Un)packing Word8
to/from 8-tuples of Bool
.
Arguments
:: Bool | least significant bit |
-> Bool | |
-> Bool | |
-> Bool | |
-> Bool | |
-> Bool | |
-> Bool | |
-> Bool | most significant bit |
-> Word8 |
Pack bits into a byte in little-endian order.
Arguments
:: 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.
