What happens if prefix generated is same for 2 keys

Lines 13 to 28 in 4984a14

	def assign_key(self, obj: "AbstractAPIKey") -> str:
	try:
	key, prefix, hashed_key = self.key_generator.generate()
	except ValueError: # Compatibility with < 1.4
	generate = typing.cast(
	typing.Callable[[], typing.Tuple[str, str]], self.key_generator.generate
	)
	key, hashed_key = generate()
	pk = hashed_key
	prefix, hashed_key = split(hashed_key)
	else:
	pk = concatenate(prefix, hashed_key)
	obj.id = pk
	obj.prefix = prefix
	obj.hashed_key = hashed_key

What happens if a duplicate prefix gets generated?
Since, in AbstractAPIKey, prefix field has unique=True, I am guessing IntegrityError would be raised.
Does this library handle that?
