#typecast_hash_to_date(value) ⇒ Date

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Creates a Date instance from a Hash with keys :year, :month, :day

Parameters:

• value (Hash, #to_mash) —

  value to be typecast

Returns:

• (Date) —

  Date constructed from hash

  ::Date.new(*extract_time(value)[0, 3])
end

#typecast_to_primitive(value) ⇒ Date

Parameters:

• value (Hash, #to_mash, #to_s) —

  value to be typecast

Returns:

• (Date) —

  Date constructed from value
