ROP Guide (Draft V1)

The original Railway Oriented Programming (ROP) blogpost can be found here: https://fsharpforfunandprofit.com/rop/

Summary

• ROP abstracts away error handling so we can pull it out of business logic
• ROP helps us remember to handle errors by failing to compile when we forget
• If you have a method than can fail, have it return a Result<T> instead
• When your method succeeds return Success
