// MetadataMatcher provides a general interface to check if a given value is matched in
// :ref:`Metadata <envoy_api_msg_core.Metadata>`. It uses `filter` and `path` to retrieve the value
// from the Metadata and then check if it's matched to the specified value.
//
// For example, for the following Metadata:
//
// .. code-block:: yaml
//
//    filter_metadata:
//      envoy.filters.http.rbac:
//        fields:
//          a:
//            struct_value:
//              fields:
//                b:
//                  struct_value:
//                    fields:
//                      c:
//                        string_value: pro
//                t:
//                  list_value:
//                    values:
//                      - string_value: m
//                      - string_value: n
//
// The following MetadataMatcher is matched as the path [a, b, c] will retrieve a string value "pro"
// from the Metadata which is matched to the specified prefix match.
//
// .. code-block:: yaml
//
//    filter: envoy.filters.http.rbac
//    path:
//    - key: a
//    - key: b
//    - key: c
//    value:
//      string_match:
//        prefix: pr
//
// The following MetadataMatcher is matched as the code will match one of the string values in the
// list at the path [a, t].
//
// .. code-block:: yaml
//
//    filter: envoy.filters.http.rbac
//    path:
//    - key: a
//    - key: t
//    value:
//      list_match:
//        one_of:
//          string_match:
//            exact: m
//
// An example use of MetadataMatcher is specifying additional metadata in envoy.filters.http.rbac to
// enforce access control based on dynamic metadata in a request. See :ref:`Permission
// <envoy_api_msg_config.rbac.v2alpha.Permission>` and :ref:`Principal
