Class Method Details

.args(message, details_hash, kwargs) ⇒ Object

Normalize the (message, details_hash, kwargs) triple that every typed-error initializer receives. Returns [message, kwargs] where:

  • message is nil or a String (never a Hash)
  • kwargs is a Hash with symbol keys, containing every key from the original details_hash and **kwargs, plus anything that was tucked inside message (when the caller passed a Hash as the first arg).

The subclass initializer then kwargs.delete(:specific_field) to pull its own fields out, and the leftover **kwargs flows to super as details:.
