@spec format_pattern(
  bundle :: Fluent.bundle(),
  message :: String.t(),
  args :: Keyword.t()
) ::
  {:ok, String.t()} | {:error, :bad_msg} | no_return()

Performs localization for given message with given bundle.

Returns ok tuple if message is succeeded Potentially can crash in the bundle that is given not match.

@spec init(locale :: Fluent.locale(), opts :: Keyword.t()) ::
  {:ok, Fluent.bundle()} | no_return()

Initializes Fluent native bundle for given locale, and returns reference to it on succeded initialization.

Available options:

• use_isolating - if set to false, removes isolation for messages. Can be used in specific environments to prevent unnesessary identation. Must be set to true in for right-to-left locale usages.

Examples:

iex> init("en")
{:ok, #Reference<...>}

@spec with_resource(bundle :: Fluent.bundle(), resource :: String.t()) ::
  :ok | {:error, :bad_resource} | no_return()

Adds new FTL resource for existing bundle.

Resource mast be valid FTL source. The function can returns :ok if resource is valid, and does not return bundle reference again, becuse data under the reference is mutable.

Examples:

iex> {:ok, bundle} = init("en")
{:ok, #Reference<...>}

iex> with_resource(bundle, "key = Translation")
:ok
