1. stripPrefix :: OsString -> OsString -> Maybe OsString

   os-string	System.OsString

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

2. stripSuffix :: OsString -> OsString -> Maybe OsString

   os-string	System.OsString

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

3. isInfixOf :: ShortByteString -> ShortByteString -> Bool

   os-string	System.OsString.Data.ByteString.Short

   Check whether one string is a substring of another.

4. isPrefixOf :: ShortByteString -> ShortByteString -> Bool

   os-string	System.OsString.Data.ByteString.Short

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

5. isSuffixOf :: ShortByteString -> ShortByteString -> Bool

   os-string	System.OsString.Data.ByteString.Short

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

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

6. stripPrefix :: ShortByteString -> ShortByteString -> Maybe ShortByteString

   os-string	System.OsString.Data.ByteString.Short

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

7. stripSuffix :: ShortByteString -> ShortByteString -> Maybe ShortByteString

   os-string	System.OsString.Data.ByteString.Short

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

8. isInfixOf :: ShortByteString -> ShortByteString -> Bool

   os-string	System.OsString.Data.ByteString.Short.Word16

   Check whether one string is a substring of another.

9. isPrefixOf :: ShortByteString -> ShortByteString -> Bool

   os-string	System.OsString.Data.ByteString.Short.Word16

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

10. isSuffixOf :: ShortByteString -> ShortByteString -> Bool

    os-string	System.OsString.Data.ByteString.Short.Word16

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

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