I enjoy this:
But yeah, that requires an
Optiontype rather thannullpointers...a?.or(b)
Kotlin go brr
a ?: bIs that Rust? Assuming
ais an Option (which would be close approximation of OP's nullable type) and assuming b is not null, then this would be closer to the original idea:It returns value of
aif it's not None rather than Option.Ah, true. Thanks.
Theoretically, it was supposed to be pseudo-code, secretly inspired by Rust, but I did get that one mixed up.
And I am actually even a fan of the word
unwrapthere, because it follows a schema and you can have your IDE auto-complete all the things you can do with anOption.In many of these other languages, you just get weird collections of symbols which you basically have to memorize and which only cover rather specific uses.
