# `Localize.RelativeUrlError`
[🔗](https://github.com/elixir-localize/localize_web/blob/main/lib/localize/exception/relative_url_error.ex#L1)

Exception returned when an `hreflang` annotation is given a URL that is not
fully qualified.

Search engines and agents ignore `rel="alternate"` links whose `href` is
relative, silently: the annotation is emitted, nothing consumes it, and the
site appears not to declare the variant at all. Returning an error surfaces
at development time what would otherwise be invisible in production.

# `t`

```elixir
@type t() :: %Localize.RelativeUrlError{
  __exception__: term(),
  locale: String.t(),
  url: String.t()
}
```

The offending URL and the locale it was annotating.
