Bimap between Word8
an an arbitrary (ordered) type. Values of type
Word8Bimap
have to be constructed carefully to contain values for
all 256 Word8
values, or the API will not be safe to use.
Synopsis
- data Word8Bimap a
- unsafeConstruct :: Ord a => [(Word8, a)] -> Word8Bimap a
- lookupL :: Word8Bimap a -> Word8 -> a
- lookupR :: Ord a => Word8Bimap a -> a -> Maybe Word8
Documentation
data Word8Bimap a Source #
Bimap where one of the keys is (of the size of) a Word8
.
unsafeConstruct :: Ord a => [(Word8, a)] -> Word8Bimap a Source #
Create a Word8Bimap
from an association list.
The list must contain all Word8
in order to make the API operating on
the result safe.
lookupL :: Word8Bimap a -> Word8 -> a Source #
Get the value corresponding to an index.
