Documentation
newtype ByteString (n :: Natural) (context :: (Type -> Type) -> Type) Source #
A ByteString which stores n bits and uses elements of a as registers, one element per register.
Bit layout is Big-endian.
Constructors
| ByteString (context (Vector n)) |
Instances
class ShiftBits a where Source #
A class for data types that support bit shift and bit cyclic shift (rotation) operations.
Minimal complete definition
(shiftBits | shiftBitsL, shiftBitsR), (rotateBits | rotateBitsL, rotateBitsR)
Methods
shiftBits :: a -> Integer -> a Source #
shiftBits performs a left shift when its agrument is greater than zero and a right shift otherwise.
shiftBitsL :: a -> Natural -> a Source #
shiftBitsR :: a -> Natural -> a Source #
rotateBits :: a -> Integer -> a Source #
rotateBits performs a left cyclic shift when its agrument is greater than zero and a right cyclic shift otherwise.
rotateBitsL :: a -> Natural -> a Source #
rotateBitsR :: a -> Natural -> a Source #
Instances
| (Symbolic c, KnownNat n) => ShiftBits (ByteString n c) Source # | |

class Resize a b where Source #
Describes types that can increase or shrink their capacity by adding zero bits to the beginning (i.e. before the higher register) or removing higher bits.
Instances
| (Symbolic c, KnownNat k, KnownNat n) => Resize (ByteString k c) (ByteString n c) Source # | |
Defined in ZkFold.Symbolic.Data.ByteString Methods resize :: ByteString k c -> ByteString n c Source # | |
| (Symbolic c, KnownNat n, KnownNat k, KnownRegisterSize r) => Resize (UInt n r c) (UInt k r c) Source # | |
reverseEndianness :: forall wordSize k c m {n}. (Symbolic c, KnownNat wordSize, n ~ (k * wordSize), (m * 8) ~ wordSize) => ByteString n c -> ByteString n c Source #
toWords :: forall m wordSize c. (Symbolic c, KnownNat wordSize) => ByteString (m * wordSize) c -> Vector m (ByteString wordSize c) Source #
A ByteString of length n can only be split into words of length wordSize if all of the following conditions are met:
1. wordSize is not greater than n;
2. wordSize is not zero;
3. The bytestring is not empty;
4. wordSize divides n.
concat :: forall k m c. Symbolic c => Vector k (ByteString m c) -> ByteString (k * m) c Source #
truncate :: forall m n c. (Symbolic c, KnownNat n, n <= m) => ByteString m c -> ByteString n c Source #
Describes types that can be truncated by dropping several bits from the end (i.e. stored in the lower registers)
append :: forall m n c. Symbolic c => KnownNat m => KnownNat n => ByteString m c -> ByteString n c -> ByteString (m + n) c Source #
emptyByteString :: FromConstant Natural (ByteString 0 c) => ByteString 0 c Source #
