foldl1 -base

foldl1 :: (Char -> Char -> Char) -> ByteString -> Char
bytestring Data.ByteString.Char8, bytestring Data.ByteString.Lazy.Char8
foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty ByteStrings.
foldl1 :: (Char -> Char -> Char) -> Text -> Char
text Data.Text, text Data.Text.Lazy
O(n) A variant of foldl that has no starting value argument, and thus must be applied to a non-empty Text. Subject to fusion.
foldl1 :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString.Lazy
foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty ByteStrings. This function is subject to array fusion.
foldl1 :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString
foldl1 is a variant of foldl that has no starting value argument, and thus must be applied to non-empty ByteStrings. This function is subject to array fusion. An exception will be thrown in the case of an empty ByteString.
foldl1' :: (Char -> Char -> Char) -> ByteString -> Char
bytestring Data.ByteString.Lazy.Char8
'foldl1\'' is like foldl1, but strict in the accumulator.
foldl1' :: (Char -> Char -> Char) -> ByteString -> Char
bytestring Data.ByteString.Char8
A strict version of foldl1
foldl1' :: (Char -> Char -> Char) -> Text -> Char
text Data.Text, text Data.Text.Lazy
O(n) A strict version of foldl1. Subject to fusion.
foldl1' :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString.Lazy
'foldl1\'' is like foldl1, but strict in the accumulator.
foldl1' :: (Word8 -> Word8 -> Word8) -> ByteString -> Word8
bytestring Data.ByteString
'foldl1\'' is like foldl1, but strict in the accumulator. An exception will be thrown in the case of an empty ByteString.
