Common data definitions and helper functions for this library.

Synopsis

BaseSystem data structures

Implements BaseSystem over base radix modulus.

Constructors

RadixSystem
Fields radixShow :: String Used to implement instance of Show. radixAlpha :: Alphabet Alphabet for the base system.

Instances details

Show RadixSystem Source #
Instance details Defined in Data.BaseSystem.Internal Methods showsPrec :: Int -> RadixSystem -> ShowS # show :: RadixSystem -> String # showList :: [RadixSystem] -> ShowS #
BaseSystem RadixSystem Source #	Implements BaseSystem for number systems built by modular arithmetic w/ the radix.
Instance details Defined in Data.BaseSystem Methods encoder :: RadixSystem -> Encoder Source # decoder :: RadixSystem -> Decoder Source #

Implements padding for encoding BitwiseSystem.

Constructors

PaddingMethod
Fields paddingChar :: Char Gives the char to use as padding. paddingResolve :: Int -> String Provides the callback to resolve the padding from # of bytes.

Implements BaseSystem over series of bit groups.

Constructors

BitwiseSystem
Fields bitwiseShow :: String String used to implement instance of Show. bitwiseAlpha :: Alphabet Base system alphabet. bitwiseSymBits :: Int # of bits per symbol bitwiseGroupBytes :: Int # of bytes to be processed into symbols in encoding. bitwiseGroupSymbols :: Int # of bytes forming a group to find padding in decoding. bitwisePadMethod :: Maybe PaddingMethod Gives the method for padding.

Instances details

Show BitwiseSystem Source #
Instance details Defined in Data.BaseSystem.Internal Methods showsPrec :: Int -> BitwiseSystem -> ShowS # show :: BitwiseSystem -> String # showList :: [BitwiseSystem] -> ShowS #
BaseSystem BitwiseSystem Source #	Implements encoder/decoder for a BitwiseSystem.

List utilities

replaceNull :: [a] -> [a] -> [a] Source #

Return the the first param if the second param is empty.

iterateInit :: (b -> b) -> (a -> b) -> a -> [b] Source #

Wraps iterate to compose with an intermediary type constructor.

Builds an Integer from ByteString.

Encode an Integer's numeric value in a ByteString as raw base2 binary values from the the Integer's bit values.

Checks if an Integral a fits within a BitwiseSystem's group.

binaryDecoder :: FinalizeBits -> Text -> DecoderBuilder -> Maybe ByteString Source #

Provides generic structure for decoding symbols into binary data ByteString.
