With the release of Go 1.18, adding generics, I thought it might be fun to make a tiny Options library to bring some of that Rustacean Panicking magic into Go.
I'd love any feedback or contributions to make it, well, _less_ crappy!
Cheers.
It's about all the operations you can chain with it:
- and_then
- ok_or_else
- map
- ...
Your implementation, and the 10 others I've seen since the release, has strictly no advantage over using `interface{}` with a `nil` check.
Go 1.18 cannot have an Option type or a Result type because its generics are painfully too restrictive:
- no switch on a generic type
- method must have no type parameter
- union types cannot be used for anything else than a type constraint
- probably other things I did not notice yet
