instance IsURI Modern.URI where
uriFromText = left displayException . mkURI
uriToText = render

Test if string contains a valid URI reference (an absolute or relative URI with optional fragment identifier).

Type class for types which can be safely cast to UriLauncher, for instance with toUriLauncher.
