Hi all,
I've never found an easy way to deal with ByteStrings.
I'm using the RSA library and it en- and decodes Data.ByteString.Lazy.ByteString.
I initially start with Strings, ie. [Char], but there is no function to convert the 2 back and forth. There is however a function which takes [Word8] to BytesString and back.
It all wouldn't be so confusing if there weren't several versions of ByteString in several modules to choose from. And a number of libraries requiring different types of ByteString.
I am sure the designers of the bytestring package had good reason for this design, is there also a webpage which explains which one to use and under what circumstances?
As a general rule you should never convert between String and bytestring. You can read bytestrings from files, or write literals using "pack" or the -XOverloadedStrings extension Converting between lazy and strict bytestrings is a representation change, and changes complexity - so be aware of what you're doing. You can do this via fromChunks or concat . toChunks. -- Don
