Exvalibur → Module-based validators

Project update 20 Mar 2019 by am-kantox / mudasobwa | Retweet this

Starting with v0.8.0 Exvalibur accepts module-based validatiors:

defmodule Validator do
  use Exvalibur, rules: [
    %{
      matches: %{currency_pair: <<"EUR", _ :: binary>>},
      conditions: %{foo: %{min: 0, max: 100}},
      guards: %{num: num > 0 and num < 100}}]
end

Validator.valid?(%{currency_pair: "EURUSD", foo: 50, num: 50})
#⇒ {:ok, %{currency_pair: "EURUSD", foo: 50, num: 50}}
Validator.valid?(%{currency_pair: "USDEUR", foo: 50, num: 50})
#⇒ :error
