Check if the value is NOT in given set

[Franky]

Hi,

(hope this question was not answered in past. I have tried to search for the answer with no luck)

Is there any nice way to check if the value is not in given set? Or at least to check if the value is not equal to some particular value (opposite of "eq")?

Example:
(schema/check (schema/not-eq 1) 1) ; leads to validation error

So far I achived something similar using coditional:
(def schema-not-equals-to-one
  (s/conditional
    #(= 1 %) <...put some validation here that always returns a validation error...>
    :else s/Any))

, but I wonder if there is anything "built-in" the library.

Regards,
Franky.

Hi Franky,

Best way I can think of currently would be to use `s/pred`, e.g.

user> (s/check (s/pred (complement #{:foo :bar}) 'allowed-value) :foo)
(not (allowed-value :foo))

Cheers,
Jason
