Returns rbnf_rules for a locale or raises an exception if there are no rules.

• locale is any Cldr.LanguageTag

• backend is any module that includes use Cldr and therefore is a Cldr backend module

Returns rbnf_rules for a locale and backend or raises an exception if there are no rules.

• locale is any locale name returned by Cldr.Rbnf.known_locale_names/1

• backend is any module that includes use Cldr and therefore is a Cldr backend module

@spec for_locale(Cldr.LanguageTag.t()) ::
  {:ok, map()} | {:error, {module(), String.t()}}

Returns {:ok, rbnf_rules} for a locale or {:error, {Cldr.NoRbnf, info}}

• locale is any t:Cldr.LanguageTag

This function reads the raw locale definition and therefore should not be called at runtime.

@spec for_locale(Cldr.Locale.locale_name() | Cldr.LanguageTag.t(), Cldr.backend()) ::
  {:ok, map()} | {:error, {module(), String.t()}}

Returns {:ok, rbnf_rules} for a locale or {:error, {Cldr.NoRbnf, info}}

• locale is any locale name returned by Cldr.Rbnf.known_locale_names/1

• backend is any module that includes use Cldr and therefore is a Cldr backend module

Returns the list of locales that that have RBNF defined

This list is the set of known locales for which there are rbnf rules defined.

Delegates to Cldr.known_rbnf_locale_names/1

@spec rule_names_for_locale!(Cldr.LanguageTag.t()) :: [atom()] | no_return()

A rule name can be used as the :format parameter in Cldr.Number.to_string/3.
