An example of an AI chatbot conversation about Haskell error handling libraries.
What are some good libraries for error handling in Haskell?
Some popular libraries for error handling in Haskell include 'Either', 'Maybe', and 'transformers'. Would you like details on any specific one?
Can you explain how to use the 'Either' type for error handling?
Sure! The 'Either' type represents a value that can be one of two types: 'Left' for an error and 'Right' for a success. You can use it to handle errors gracefully.
What about using 'Maybe'? How does it differ from 'Either'?
'Maybe' is simpler; it represents a value that can either be 'Just' a value or 'Nothing'. It's useful when you want to indicate the absence of a value without needing an error message.
Are there any libraries that combine these concepts?
Yes, libraries like 'errors' and 'exceptions' provide more advanced error handling features, combining 'Either' and 'Maybe' with additional functionality.
