Typescript type/interface for strings of a given length

Question

Say my function f takes an argument, x, of type string. But not any string, only strings of length n.

Is it possible to enforce this using the type system?

No, it is not possible to do this in Typescript as types.

There is an open proposal for regex-validated types though, but nothing you can do currently.
