[racket] Run-time record access

I'm hoping to implement the following function to access arbitrary struct

;; Compute `[st]-field-name st`, where
;; [st] is the name of the struct type of `st`
(define (runtime-get st field-name)
  (-> struct? string? any/c)
  (error "not implemented"))

Is this possible? I fear I can't use a macro because I don't know exactly
which struct I'll get at runtime.
