Opts

  • opts([{:list, :atom}, :keyword]): A list of opts accepted, or a keyword of opt name to opt type - Default: []
  • required({:list, :atom}): A list of required opts (all of which must be in opts as well) - Default: []
  • defaults(:keyword): A keyword list of option name to a default value. Values must pass type rules - Default: []
  • extra_keys?(:boolean): If enabled, extra keys not specified by the schema do not fail validation - Default: false
  • custom(:keyword): A keyword list of option name (for errors) and custom validations. See README - Default: []
  • describe(:keyword): A keyword list of option names to short descriptions (like these) - Default: []

A custom validation is run on the types provided at schema creation time, to ensure they are all valid types.
