module MIME::Types::Columnar
MIME::Types::Columnar is used to extend a MIME::Types container to load data by columns instead of from JSON or YAML. Column loads of MIME types loaded through the columnar store are synchronized with a Mutex.
MIME::Types::Columnar is not intended to be used directly, but will be added to an instance of MIME::Types when it is loaded with MIME::Types::Loader#load_columnar.
