defmodule Localize.CurrencyNotLocalizedError do
  @moduledoc """
  Exception raised when a known currency code has no localized
  data in the requested locale.

  Distinct from `Localize.UnknownCurrencyError`, which signals
  that the currency code itself is not a recognised ISO 4217 or
  registered custom currency. This error means the code is valid
  but the locale's CLDR currency map has no entry for it.

  Pass `fallback: true` to `Localize.Currency.currency_for_code/2`
  to walk the CLDR locale fallback chain (and the application
  default locale) before failing with this error.
