What are the differences between Haskell's Either type and Maybe type?
An example of an AI chatbot conversation about Haskell's Either type and Maybe type differences.
What are the differences between Haskell's Either type and Maybe type?
The Maybe type is used to represent a value that might be absent, while Either can represent two possibilities, typically an error or a success.
Can you give me an example of how to use Either in Haskell?
Sure! Here's a simple example: data Result = Success Int | Error String. You can use it to return either a successful result or an error message.
When should I use Either instead of Maybe?
Use Either when you need to convey more information about failure, like an error message, while Maybe is sufficient for just indicating absence.
Are there any performance differences between the two?
Generally, the performance difference is negligible, but Either may have a slight overhead due to carrying more information.
