method DynHandle.check

Would text (JSON, or plain text for a str) be accepted as a value of this field?

Example:

dynamic Limits {
  rps: u32 = 100
  title: str = "shop"
}

fn main() io {
  let l = Limits.get()
  match l.rps.check("250") {
    str s => print("ok {s}")
    DynError _ => print("bad")
  }
  match l.rps.check("-1") {
    str s => print("ok {s}")
    DynError _ => print("bad")
  }
}

ok 250
bad
