+// URL that describes the type of the serialized message.
+//
+// Protobuf library provides support to pack/unpack Any values in the form

+//
+// Example 1: Pack and unpack a message in C++.
+//
+//     Foo foo = ...;
+//     Any any;
+//     any.PackFrom(foo);
+//     ...
+//     if (any.UnpackTo(&foo)) {

+//     ...
+//     if (any.is(Foo.class)) {

+//     if (any.isSameTypeAs(Foo.getDefaultInstance())) {

+//     }

+//  Example 3: Pack and unpack a message in Python.
+//
+//     foo = Foo(...)
+//     any = Any()
+//     any.Pack(foo)
+//     ...
+//     if any.Is(Foo.DESCRIPTOR):

+// methods only use the fully qualified type name after the last '/'
+// in the type URL, for example "foo.bar.com/x/y.z" will yield type
+// name "y.z".
+//
+// JSON
+// ====
+// The JSON representation of an `Any` value uses the regular
+// representation of the deserialized, embedded message, with an
+// additional field `@type` which contains the type URL. Example:
+//
+//     package google.profile;

+//       "firstName": <string>,
+//       "lastName": <string>
+//     }
+//
+// If the embedded message type is well-known and has a custom JSON
+// representation, that representation will be embedded adding a field
+// `value` which holds the custom JSON in addition to the `@type`
+// field. Example (for message [google.protobuf.Duration][]):
+//
+//     {
+//       "@type": "type.googleapis.com/google.protobuf.Duration",
+//       "value": "1.212s"
+//     }
+swagger:model LeaderHealthCheckDefaultBodyDetailsItems0

+	// the fully qualified name of the type (as in
+	// `path/google.protobuf.Duration`). The name should be in a canonical form
+	// (e.g., leading "." is not accepted).
+	//
+	// In practice, teams usually precompile into the binary all types that they
+	// expect it to use in the context of Any. However, for URLs which use the
+	// scheme `http`, `https`, or no scheme, one can optionally set up a type

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }",

The last segment of the URL's path must represent\nthe fully qualified name of the type (as in\n`path/google.protobuf.Duration`). The name should be in a canonical form\n(e.g., leading \".\" is not accepted).\n\nIn practice, teams usually precompile into the binary all types that they\nexpect it to use in the context of Any. However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types. (Use versioned type names to manage\n  breaking changes.)\n\nNote: this functionality is not currently available in the official\nprotobuf release, and it is not used for type URLs beginning with\ntype.googleapis.com. As of May 2023, there are no widely used type server\nimplementations and no plans to implement one.\n\nSchemes other than `http`, `https` (or the empty scheme) might be\nused with implementation specific semantics.",

Example:\n\n    package google.profile;\n    message Person {\n      string first_name = 1;\n      string last_name = 2;\n    }\n\n    {\n      \"@type\": \"type.googleapis.com/google.profile.Person\",\n      \"firstName\": \u003cstring\u003e,\n      \"lastName\": \u003cstring\u003e\n    }\n\nIf the embedded message type is well-known and has a custom JSON\nrepresentation, that representation will be embedded adding a field\n`value` which holds the custom JSON in addition to the `@type`\nfield. Example (for message [google.protobuf.Duration][]):\n\n    {\n      \"@type\": \"type.googleapis.com/google.protobuf.Duration\",\n      \"value\": \"1.212s\"\n    }",

The name should be in a canonical form\n(e.g., leading \".\" is not accepted).\n\nIn practice, teams usually precompile into the binary all types that they\nexpect it to use in the context of Any. However, for URLs which use the\nscheme `http`, `https`, or no scheme, one can optionally set up a type\nserver that maps type URLs to message definitions as follows:\n\n* If no scheme is provided, `https` is assumed.\n* An HTTP GET on the URL must yield a [google.protobuf.Type][]\n  value in binary format, or produce an error.\n* Applications are allowed to cache lookup results based on the\n  URL, or have them precompiled into a binary to avoid any\n  lookup. Therefore, binary compatibility needs to be preserved\n  on changes to types.
