Croma.SubtypeOfTuple (croma v0.11.1) View Source

Helper module to define tuple-based types. The following members are generated by use Croma.SubtypeOfTuple:

• @type t
• @spec valid?(term) :: boolean
• If any of :elem_modules exports new/1,
  • @spec new(term) :: Croma.Result.t(t)
  • @spec new!(term) :: t

Options:

• :elem_modules - A list of type modules for tuple elements.
• :default - Default value for this type. Passing this option generates default/0.

Examples

defmodule MyTuple do
  use Croma.SubtypeOfTuple, elem_modules: [MyInt, MyString]
end
