1. stripSuffix :: ByteString -> ByteString -> Maybe ByteString

   bytestring	Data.ByteString.Char8

   O(n) The stripSuffix function takes two ByteStrings and returns Just the remainder of the second iff the first is its suffix, and otherwise Nothing.

2. isPrefixOf :: ByteString -> ByteString -> Bool

   bytestring	Data.ByteString.Lazy

   O(n) The isPrefixOf function takes two ByteStrings and returns True iff the first is a prefix of the second.

3. isSuffixOf :: ByteString -> ByteString -> Bool

   bytestring	Data.ByteString.Lazy

   O(n) The isSuffixOf function takes two ByteStrings and returns True iff the first is a suffix of the second. The following holds:

   isSuffixOf x y == reverse x `isPrefixOf` reverse y
   

4. stripPrefix :: ByteString -> ByteString -> Maybe ByteString

   bytestring	Data.ByteString.Lazy

   O(n) The stripPrefix function takes two ByteStrings and returns Just the remainder of the second iff the first is its prefix, and otherwise Nothing.

5. stripSuffix :: ByteString -> ByteString -> Maybe ByteString

   bytestring	Data.ByteString.Lazy

   O(n) The stripSuffix function takes two ByteStrings and returns Just the remainder of the second iff the first is its suffix, and otherwise Nothing.

6. isPrefixOf :: ByteString -> ByteString -> Bool

   bytestring	Data.ByteString.Lazy.Char8

   O(n) The isPrefixOf function takes two ByteStrings and returns True iff the first is a prefix of the second.

7. isSuffixOf :: ByteString -> ByteString -> Bool

   bytestring	Data.ByteString.Lazy.Char8

   O(n) The isSuffixOf function takes two ByteStrings and returns True iff the first is a suffix of the second. The following holds:

   isSuffixOf x y == reverse x `isPrefixOf` reverse y
   

8. stripPrefix :: ByteString -> ByteString -> Maybe ByteString

   bytestring	Data.ByteString.Lazy.Char8

   O(n) The stripPrefix function takes two ByteStrings and returns Just the remainder of the second iff the first is its prefix, and otherwise Nothing.

9. stripSuffix :: ByteString -> ByteString -> Maybe ByteString

   bytestring	Data.ByteString.Lazy.Char8

   O(n) The stripSuffix function takes two ByteStrings and returns Just the remainder of the second iff the first is its suffix, and otherwise Nothing.

10. isInfixOf :: ShortByteString -> ShortByteString -> Bool

    bytestring	Data.ByteString.Short

    Check whether one string is a substring of another.
