newtype Offset ty #

Offset in a data structure consisting of elements of type ty.

Int is a terrible backing type which is hard to get away from, considering that GHC/Haskell are mostly using this for offset. Trying to bring some sanity by a lightweight wrapping.

type Offset8 = Offset Word8 #

Offset in bytes used for memory addressing (e.g. in a vector, string, ..)

sentinel :: Offset ty #

offsetOfE :: CountOf Word8 -> Offset ty -> Offset8 #

offsetPlusE :: Offset ty -> CountOf ty -> Offset ty #

offsetMinusE :: Offset ty -> CountOf ty -> Offset ty #

offsetRecast :: CountOf Word8 -> CountOf Word8 -> Offset ty -> Offset ty2 #

offsetCast :: Proxy (a -> b) -> Offset a -> Offset b #

offsetSub :: Offset a -> Offset a -> Offset a #

subtract 2 CountOf values of the same type.

m need to be greater than n, otherwise negative count error ensue use the safer (-) version if unsure.

offsetShiftL :: Int -> Offset ty -> Offset ty2 #

offsetShiftR :: Int -> Offset ty -> Offset ty2 #

sizeCast :: Proxy (a -> b) -> CountOf a -> CountOf b #

sizeLastOffset :: CountOf a -> Offset a #

sizeAsOffset :: CountOf a -> Offset a #

sizeSub :: CountOf a -> CountOf a -> CountOf a #

subtract 2 CountOf values of the same type.

m need to be greater than n, otherwise negative count error ensue use the safer (-) version if unsure.

countOfRoundUp :: Int -> CountOf ty -> CountOf ty #

alignment need to be a power of 2

offsetAsSize :: Offset a -> CountOf a #

(+.) :: Offset ty -> Int -> Offset ty #

(.==#) :: Offset ty -> CountOf ty -> Bool #

newtype CountOf ty #

CountOf of a data structure.

More specifically, it represents the number of elements of type ty that fit into the data structure.

>>> length (fromList ['a', 'b', 'c', '🌟']) :: CountOf Char
CountOf 4

Same caveats as Offset apply here.
