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

• @type t
• @spec validate(term) :: Croma.Result.t(t)

Options:

• :elem_module - A module that defines the type of the element. The module must provide @type t and @spec validate(term) :: Croma.Result.t(t).
• :min_length - Minimum length of valid values of this type (inclusive).
• :max_length - Maximum length of valid values of this type (inclusive).
• :default - Default value for this type. Passing this option generates default/0.

Examples

defmodule MyList do
  use Croma.SubtypeOfList, elem_module: MyInt, default: []
end
