newtype Offset ty Source #

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 Source #

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

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.

subtract 2 CountOf values of the same type.

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

alignment need to be a power of 2

offsetAsSize :: Offset a -> CountOf a Source #

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

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

newtype CountOf ty Source #

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.
