def content_types_for(from_settings)
  from_settings.presence || DEFAULTS
end

.media_type(content_type) ⇒ Object

The media type of a content-type header: the part before any ; parameters, with surrounding whitespace removed (e.g. 'text/html' for 'text/html; charset=utf-8'). Returns nil for a nil content type. Skips the split (and its allocation) when there are no parameters, which is the common case.
