Contracts or Exceptions?

[Mike Linford]

Hello,

So I'm writing a function for a library. It takes a struct as an 
argument. The struct's fields can't just be any old values, though. The 
function won't work if some of the fields are weird. It could return an 
erroneous value, or even crash. 

The thing is, though, that I can't tell whether the best approach is to 
use an in-contract or throw an exception if it doesn't pass my test. What 
would you guys recommend?
