foldr1 -text

foldr1 :: (a -> a -> a) -> [a] -> a
base Prelude, base Data.List
foldr1 is a variant of foldr that has no starting value argument, and thus must be applied to non-empty lists.
foldr1 :: Foldable t => (a -> a -> a) -> t a -> a
base Data.Foldable
foldr1 :: (Char -> Char -> Char) -> ByteString -> Char
bytestring Data.ByteString.Char8, bytestring Data.ByteString.Lazy.Char8
foldr1 is a variant of foldr that has no starting value argument, and thus must be applied to non-empty ByteStrings
foldr1 :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString.Lazy
foldr1 is a variant of foldr that has no starting value argument, and thus must be applied to non-empty ByteStrings
foldr1 :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString
foldr1 is a variant of foldr that has no starting value argument, and thus must be applied to non-empty ByteStrings An exception will be thrown in the case of an empty ByteString.
foldr1' :: (Char -> Char -> Char) -> ByteString -> Char
bytestring Data.ByteString.Char8
A strict variant of foldr1
foldr1' :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString
'foldr1\'' is a variant of foldr1, but is strict in the accumulator.
