Croma.SubtypeOfNumber (croma v0.11.1) View Source

Helper module to define number-based (integer or float) types. The following members are generated by use Croma.SubtypeOfNumber:

• @type t
• @spec valid?(term) :: boolean

Options:

• :min - Minimum value of this type (inclusive).
• :max - Maximum value of this type (inclusive).
• :default - Default value for this type. Passing this option generates default/0.

  use Croma.SubtypeOfNumber, min: 0, max: 3.141592653589793, default: 0
end
