WebThe type of this thing is pretty horrific. I think you need dependent types to express the relation between the numeric argument and the length of resulting tupple.

WebOct 21, 2024 · But Rust, like many other languages with strong static typing, does this checks itself at compile-time. Well, you still can somewhat mimic "dynamic typechecking" by using Any trait and asking the value at runtime whether it is of certain type or not, but this is extremely niche case. Usually, you don't want to check the types.
