   :widths: 1 1 1 1 4
   :header-rows: 1

   * - Name
     - Type
     - Mandatory
     - Default
     - Description
   * - ``protos``
     - ``label_list``
     - true
     - 
     - List of labels that provide the ``ProtoInfo`` provider (such as ``proto_library`` from ``rules_proto``)
   * - ``options``
     - ``string_list_dict``
     - false
     - ``[]``
     - Extra options to pass to plugins, as a dict of plugin label -> list of strings. The key * can be used exclusively to apply to all plugins
   * - ``verbose``
     - ``int``
     - false
     - ``0``
     - The verbosity level. Supported values and results are 0: Show nothing, 1: Show command, 2: Show command and sandbox after running protoc, 3: Show command and sandbox before and after running protoc, 4. Show env, command, expected outputs and sandbox before and after running protoc
   * - ``prefix_path``
     - ``string``
     - false
     - ``""``
     - Path to prefix to the generated files in the output directory
   * - ``extra_protoc_args``
     - ``string_list``
     - false
     - ``[]``
     - A list of extra args to pass directly to protoc, not as plugin options
   * - ``extra_protoc_files``
     - ``label_list``
     - false
     - ``[]``
     - List of labels that provide extra files to be available during protoc execution
   * - ``output_mode``
     - ``string``
     - false
     - ``PREFIXED``
     - The output mode for the target. PREFIXED (the default) will output to a directory named by the target within the current package root, NO_PREFIX will output directly to the current package. Using NO_PREFIX may lead to conflicting writes
