Well, getters are not an official concept in Rust. You can do whatever works best in your case.
Just worth pointing out that a method with a return value of
OptionᐸVecᐸStringᐳᐳ
wouldn't be really a getter, as you must be constructing values, or moving ownership, or cloning. None of these actions conceptually belong to a getter.Also, you should be clear on the what the
Option
abstraction means. Does it mean the vector is empty? Does it mean the vector does not exist or some sort of null (FFI ore serialization contexts)? And make sure the code does what you expect it to do.
