// any.Pack(foo)
// ...
// if any.Is(Foo.DESCRIPTOR):
// any.Unpack(foo)
// ...
//
// The pack methods provided by protobuf library will by default use
// 'type.googleapis.com/full.type.name' as the type URL and the unpack
// 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;
// message Person {
// string first_name = 1;
// string last_name = 2;
// }
//
// {
// "@type": "type.googleapis.com/google.profile.Person",
// "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"
// }
//
type Any struct {
// A URL/resource name whose content describes the type of the
// serialized protocol buffer message.
//
// For URLs which use the scheme `http`, `https`, or no scheme, the
// following restrictions and interpretations apply:
//
// * If no scheme is provided, `https` is assumed.
// * The last segment of the URL's path must represent 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).
// * An HTTP GET on the URL must yield a [google.protobuf.Type][]
// value in binary format, or produce an error.
// * Applications are allowed to cache lookup results based on the
// URL, or have them precompiled into a binary to avoid any
// lookup. Therefore, binary compatibility needs to be preserved
// on changes to types. (Use versioned type names to manage
// breaking changes.)
//
// Schemes other than `http`, `https` (or the empty scheme) might be
// used with implementation specific semantics.
//
TypeUrl string `protobuf:"bytes,1,opt,name=type_url,json=typeUrl,proto3" json:"type_url,omitempty"`
// Must be a valid serialized protocol buffer of the above specified type.
Value []byte `protobuf:"bytes,2,opt,name=value,proto3" json:"value,omitempty"`

// A Duration represents a signed, fixed-length span of time represented
// as a count of seconds and fractions of seconds at nanosecond
// resolution. It is independent of any calendar and concepts like "day"
// or "month". It is related to Timestamp in that the difference between

// from a Timestamp. Range is approximately +-10,000 years.
//
// Example 1: Compute Duration from two Timestamps in pseudo code.

// Timestamp start = ...;

// Duration duration = ...;
//
// duration.seconds = end.seconds - start.seconds;

// Example 2: Compute Timestamp from Timestamp + Duration in pseudo code.

// `FieldMask` represents a set of symbolic field paths, for example:
//
// paths: "f.a"
// paths: "f.b.d"
//
// Here `f` represents a field in some root message, `a` and `b`
// fields in the message found in `f`, and `d` a field found in the
// message in `f.b`.
//
// Field masks are used to specify a subset of fields that should be
// returned by a get operation or modified by an update operation.
// Field masks also have a custom JSON encoding (see below).
//
// # Field Masks in Projections
//
// When used in the context of a projection, a response message or
// sub-message is filtered by the API to only contain those fields as
// specified in the mask. For example, if the mask in the previous
// example is applied to a response message as follows:
//
// f {
// a : 22
// b {
// d : 1
// x : 2
// }
// y : 13
// }
// z: 8
//
// The result will not contain specific values for fields x,y and z
// (their value will be set to the default, and omitted in proto text
// output):
//
//
// f {
// a : 22
// b {
// d : 1
// }
// }
//
// A repeated field is not allowed except at the last position of a
// field mask.
//
// If a FieldMask object is not present in a get operation, the
// operation applies to all fields (as if a FieldMask of all fields
// had been specified).
//
// Note that a field mask does not necessarily apply to the
// top-level response message. In case of a REST get operation, the
// field mask applies directly to the response, but in case of a REST
// list operation, the mask instead applies to each individual message
// in the returned resource list. In case of a REST custom method,
// other definitions may be used. Where the mask applies will be
// clearly documented together with its declaration in the API. In
// any case, the effect on the returned resource/resources is required
// behavior for APIs.
//
// # Field Masks in Update Operations
//
// A field mask in update operations specifies which fields of the
// targeted resource are going to be updated. The API is required
// to only change the values of the fields as specified in the mask
// and leave the others untouched. If a resource is passed in to
// describe the updated values, the API ignores the values of all
// fields not covered by the mask.
//
// If a repeated field is specified for an update operation, the existing
// repeated values in the target resource will be overwritten by the new values.
// Note that a repeated field is only allowed in the last position of a field
// mask.
//
// If a sub-message is specified in the last position of the field mask for an
// update operation, then the existing sub-message in the target resource is
// overwritten. Given the target message:
//
// f {
// b {
// d : 1
// x : 2
// }
// c : 1
// }
//
// And an update message:
//
// f {
// b {
// d : 10
// }
// }
//
// then if the field mask is:
//
// paths: "f.b"
//
// then the result will be:
//
// f {
// b {
// d : 10
// }
// c : 1
// }
//
// However, if the update mask was:
//
// paths: "f.b.d"
//
// then the result would be:
//
// f {
// b {
// d : 10
// x : 2
// }
// c : 1
// }
//
// In order to reset a field's value to the default, the field must
// be in the mask and set to the default value in the provided resource.
// Hence, in order to reset all fields of a resource, provide a default
// instance of the resource and set all fields in the mask, or do
// not provide a mask as described below.
//
// If a field mask is not present on update, the operation applies to
// all fields (as if a field mask of all fields has been specified).
// Note that in the presence of schema evolution, this may mean that
// fields the client does not know and has therefore not filled into
// the request will be reset to their default. If this is unwanted
// behavior, a specific service may require a client to always specify
// a field mask, producing an error if not.
//
// As with get operations, the location of the resource which
// describes the updated values in the request message depends on the
// operation kind. In any case, the effect of the field mask is
// required to be honored by the API.
//
// ## Considerations for HTTP REST
//
// The HTTP kind of an update operation which uses a field mask must
// be set to PATCH instead of PUT in order to satisfy HTTP semantics
// (PUT must only be used for full updates).
//
// # JSON Encoding of Field Masks
//
// In JSON, a field mask is encoded as a single string where paths are
// separated by a comma. Fields name in each path are converted
// to/from lower-camel naming conventions.
//
// As an example, consider the following message declarations:
//
// message Profile {
// User user = 1;
// Photo photo = 2;
// }
// message User {
// string display_name = 1;
// string address = 2;
// }
//
// In proto a field mask for `Profile` may look as such:
//
// mask {
// paths: "user.display_name"
// paths: "photo"
// }
//
// In JSON, the same mask is represented as below:
//
// {
// mask: "user.displayName,photo"
// }
//
// # Field Masks and Oneof Fields
//
// Field masks treat fields in oneofs just as regular fields. Consider the
// following message:
//
// message SampleMessage {
// oneof test_oneof {
// string name = 4;
// SubMessage sub_message = 9;
// }
// }
//
// The field mask can be:
//
// mask {
// paths: "name"
// }
//
// Or:
//
// mask {
// paths: "sub_message"
// }
//
// Note that oneof type names ("test_oneof" in this case) cannot be used in
// paths.
