The static
Result.success
and Result.failure
functions should be usable anywhere success
/failure
were, while also allowing you to explicitly specify the type (without resorting to as
or a temporary variable) should the need arise.

Going to close this out for now, but feel free to reopen if there’s cases that the static
functions don’t handle.

The static functions are fine, mostly I was looking to save a few characters. Plus I hadn't even considered this which is nice
while also allowing you to explicitly specify the type (without resorting to as or a temporary variable) should the need arise
from result.
Note that you can also write .success(…)
/.failure(…)
anywhere that Swift can infer the return type:
func yep() -> Result<String, String> {
return .success("👍")
}
let nope: Result<String, String> = .failure("👎")
from result.
Whoa, I thought that syntax was just for enum cases. It makes sense when I think about it though. They're both static properties/methods that need to be bound to a type.
from result.
Yep. Caveat lector: there are some corner cases where they can make compilation slow down unreasonably. I use the notation quite heavily myself, tho.
