Abstract Value Members

  1. abstract def from(cursor: ConfigCursor, options: Seq[String]): Result[Action]

    Given a ConfigCursor for the sealed family, disambiguate and return what should be performed when trying to read one of the provided coproduct options.

    Given a ConfigCursor for the sealed family, disambiguate and return what should be performed when trying to read one of the provided coproduct options. This method can decide either to:

    This method can return a Left if the hint fails to produce a valid CoproductHint.Action.

    cursor

    a ConfigCursor at the sealed family option

    options

    the names of the coproduct options for the given type

    returns

    a ConfigReader.Result of CoproductHint.Action as defined above.

  2. abstract def to(value: ConfigValue, name: String): ConfigValue

    Given the ConfigValue for a specific class or coproduct option, encode disambiguation information and return a config for the sealed family or coproduct.

    Given the ConfigValue for a specific class or coproduct option, encode disambiguation information and return a config for the sealed family or coproduct.

    value

    the ConfigValue of the class or coproduct option

    name

    the name of the class or coproduct option

    returns

    the config for the sealed family or coproduct wrapped in a Right, or a Left with the failure if some error occurred.
