Documentation
foldl1' :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8 #
'foldl1\'' is like foldl1
, but strict in the accumulator.
An exception will be thrown in the case of an empty ByteString.
foldr1 :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8 #
foldr1
is a variant of foldr
that has no starting value argument,
and thus must be applied to non-empty ByteString
s
An exception will be thrown in the case of an empty ByteString.
foldr1' :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8 #
'foldr1\'' is a variant of foldr1
, but is strict in the
accumulator.
head :: ByteString -> Word8 #
O(1) Extract the first element of a ByteString, which must be non-empty. An exception will be thrown in the case of an empty ByteString.
init :: ByteString -> ByteString #
O(1) Return all the elements of a ByteString
except the last one.
An exception will be thrown in the case of an empty ByteString.
last :: ByteString -> Word8 #
O(1) Extract the last element of a ByteString, which must be finite and non-empty. An exception will be thrown in the case of an empty ByteString.
maximum :: ByteString -> Word8 #
O(n) maximum
returns the maximum value from a ByteString
This function will fuse.
An exception will be thrown in the case of an empty ByteString.
minimum :: ByteString -> Word8 #
O(n) minimum
returns the minimum value from a ByteString
This function will fuse.
An exception will be thrown in the case of an empty ByteString.
tail :: ByteString -> ByteString #
O(1) Extract the elements after the head of a ByteString, which must be non-empty. An exception will be thrown in the case of an empty ByteString.
