// For convenience, the Opaque API also offers Builders, which allow for a
// direct translation of struct initialization. However, because Builders use

// with nil message. The above code would need to be translated with help of the

// Package proto provides functions operating on protocol buffer messages.
//
// For documentation on protocol buffers in general, see:
// https://protobuf.dev.
//
// For a tutorial on using protocol buffers with Go, see:
// https://protobuf.dev/getting-started/gotutorial.
//
// For a guide to generated Go protocol buffer code, see:
// https://protobuf.dev/reference/go/go-generated.
//
// # Binary serialization
//
// This package contains functions to convert to and from the wire format,
// an efficient binary serialization of protocol buffers.
//
// - [Size] reports the size of a message in the wire format.
//
// - [Marshal] converts a message to the wire format.
// The [MarshalOptions] type provides more control over wire marshaling.
//
// - [Unmarshal] converts a message from the wire format.
// The [UnmarshalOptions] type provides more control over wire unmarshaling.
//
// # Basic message operations
//
// - [Clone] makes a deep copy of a message.
//
// - [Merge] merges the content of a message into another.
//
// - [Equal] compares two messages. For more control over comparisons
// and detailed reporting of differences, see package
// [google.golang.org/protobuf/testing/protocmp].
//
// - [Reset] clears the content of a message.
//
// - [CheckInitialized] reports whether all required fields in a message are set.
//
// # Optional scalar constructors
//
// The API for some generated messages represents optional scalar fields
// as pointers to a value. For example, an optional string field has the
// Go type *string.
//
// - [Bool], [Int32], [Int64], [Uint32], [Uint64], [Float32], [Float64], and [String]
// take a value and return a pointer to a new instance of it,
// to simplify construction of optional field values.
//
// Generated enum types usually have an Enum method which performs the
// same operation.
//
// Optional scalar fields are only supported in proto2.
//
// # Extension accessors
//
// - [HasExtension], [GetExtension], [SetExtension], and [ClearExtension]
// access extension field values in a protocol buffer message.
//
// Extension fields are only supported in proto2.
//
// # Related packages
//
// - Package [google.golang.org/protobuf/encoding/protojson] converts messages to
// and from JSON.
//
// - Package [google.golang.org/protobuf/encoding/prototext] converts messages to
// and from the text format.
//
// - Package [google.golang.org/protobuf/reflect/protoreflect] provides a
// reflection interface for protocol buffer data types.
//
// - Package [google.golang.org/protobuf/testing/protocmp] provides features
// to compare protocol buffer messages with the [github.com/google/go-cmp/cmp]
// package.
//
// - Package [google.golang.org/protobuf/types/dynamicpb] provides a dynamic
// message type, suitable for working with messages where the protocol buffer
// type is only known at runtime.
//
// This module contains additional packages for more specialized use cases.
// Consult the individual package documentation for details.

// The Timestamp message represents a timestamp,
// an instant in time since the Unix epoch (January 1st, 1970).
//
// # Conversion to a Go Time
//
// The AsTime method can be used to convert a Timestamp message to a
// standard Go time.Time value in UTC:
//
// t := ts.AsTime()
// ... // make use of t as a time.Time
//
// Converting to a time.Time is a common operation so that the extensive
// set of time-based operations provided by the time package can be leveraged.
// See https://golang.org/pkg/time for more information.
//
// The AsTime method performs the conversion on a best-effort basis. Timestamps
// with denormal values (e.g., nanoseconds beyond 0 and 99999999, inclusive)
// are normalized during the conversion to a time.Time. To manually check for
// invalid Timestamps per the documented limitations in timestamp.proto,
// additionally call the CheckValid method:
//
// if err := ts.CheckValid(); err != nil {
// ... // handle error
// }
//
// # Conversion from a Go Time
//
// The timestamppb.New function can be used to construct a Timestamp message
// from a standard Go time.Time value:
//
// ts := timestamppb.New(t)
// ... // make use of ts as a *timestamppb.Timestamp
//
// In order to construct a Timestamp representing the current time, use Now:
//
// ts := timestamppb.Now()

// A Timestamp represents a point in time independent of any time zone or local
// calendar, encoded as a count of seconds and fractions of seconds at
// nanosecond resolution. The count is relative to an epoch at UTC midnight on
// January 1, 1970, in the proleptic Gregorian calendar which extends the
// Gregorian calendar backwards to year one.
//
// All minutes are 60 seconds long. Leap seconds are "smeared" so that no leap
// second table is needed for interpretation, using a [24-hour linear
// smear](https://developers.google.com/time/smear).
//
// The range is from 0001-01-01T00:00:00Z to 9999-12-31T23:59:59.999999999Z. By
// restricting to that range, we ensure that we can convert to and from [RFC
// 3339](https://www.ietf.org/rfc/rfc3339.txt) date strings.
//
// # Examples
//
// Example 1: Compute Timestamp from POSIX `time()`.
//
// Timestamp timestamp;
// timestamp.set_seconds(time(NULL));
// timestamp.set_nanos(0);
//
// Example 2: Compute Timestamp from POSIX `gettimeofday()`.
//
// struct timeval tv;
// gettimeofday(&tv, NULL);
//
// Timestamp timestamp;
// timestamp.set_seconds(tv.tv_sec);
// timestamp.set_nanos(tv.tv_usec * 1000);
//
// Example 3: Compute Timestamp from Win32 `GetSystemTimeAsFileTime()`.
//
// FILETIME ft;
// GetSystemTimeAsFileTime(&ft);
// UINT64 ticks = (((UINT64)ft.dwHighDateTime) << 32) | ft.dwLowDateTime;
//
// // A Windows tick is 100 nanoseconds. Windows epoch 1601-01-01T00:00:00Z
// // is 11644473600 seconds before Unix epoch 1970-01-01T00:00:00Z.
// Timestamp timestamp;
// timestamp.set_seconds((INT64) ((ticks / 10000000) - 11644473600LL));
// timestamp.set_nanos((INT32) ((ticks % 10000000) * 100));
//
// Example 4: Compute Timestamp from Java `System.currentTimeMillis()`.
//
// long millis = System.currentTimeMillis();
//
// Timestamp timestamp = Timestamp.newBuilder().setSeconds(millis / 1000)
// .setNanos((int) ((millis % 1000) * 1000000)).build();
//
// Example 5: Compute Timestamp from Java `Instant.now()`.
//
// Instant now = Instant.now();
//
// Timestamp timestamp =
// Timestamp.newBuilder().setSeconds(now.getEpochSecond())
// .setNanos(now.getNano()).build();
//
// Example 6: Compute Timestamp from current time in Python.
//
// timestamp = Timestamp()
// timestamp.GetCurrentTime()
//
// # JSON Mapping
//
// In JSON format, the Timestamp type is encoded as a string in the
// [RFC 3339](https://www.ietf.org/rfc/rfc3339.txt) format. That is, the
// format is "{year}-{month}-{day}T{hour}:{min}:{sec}[.{frac_sec}]Z"
// where {year} is always expressed using four digits while {month}, {day},
// {hour}, {min}, and {sec} are zero-padded to two digits each. The fractional
// seconds, which can go up to 9 digits (i.e. up to 1 nanosecond resolution),
// are optional. The "Z" suffix indicates the timezone ("UTC"); the timezone
// is required. A proto3 JSON serializer should always use UTC (as indicated by
// "Z") when printing the Timestamp type and a proto3 JSON parser should be
// able to accept both UTC and other timezones (as indicated by an offset).
//
// For example, "2017-01-15T01:30:15.01Z" encodes 15.01 seconds past
// 01:30 UTC on January 15, 2017.
//
// In JavaScript, one can convert a Date object to this format using the
// standard
// [toISOString()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toISOString)
// method. In Python, a standard `datetime.datetime` object can be converted
// to this format using
// [`strftime`](https://docs.python.org/2/library/time.html#time.strftime) with
// the time format spec '%Y-%m-%dT%H:%M:%S.%fZ'. Likewise, in Java, one can use
// the Joda Time's [`ISODateTimeFormat.dateTime()`](
// http://joda-time.sourceforge.net/apidocs/org/joda/time/format/ISODateTimeFormat.html#dateTime()
// ) to obtain a formatter capable of generating timestamps in this format.

// source: google/protobuf/any.proto
// Package anypb contains generated types for google/protobuf/any.proto.
//
// The Any message is a dynamic representation of any other message value.
// It is functionally a tuple of the full name of the remote message type and
// the serialized bytes of the remote message value.
//
// # Constructing an Any
//
// An Any message containing another message value is constructed using New:
//
// any, err := anypb.New(m)
// if err != nil {
// ... // handle error
// }
// ... // make use of any
//
// # Unmarshaling an Any
//
// With a populated Any message, the underlying message can be serialized into
// a remote concrete message value in a few ways.
//
// If the exact concrete type is known, then a new (or pre-existing) instance
// of that message can be passed to the UnmarshalTo method:
//
// m := new(foopb.MyMessage)
// if err := any.UnmarshalTo(m); err != nil {
// ... // handle error
// }
// ... // make use of m
//
// If the exact concrete type is not known, then the UnmarshalNew method can be
// used to unmarshal the contents into a new instance of the remote message type:
//
// m, err := any.UnmarshalNew()
// if err != nil {
// ... // handle error
// }
// ... // make use of m
//
// UnmarshalNew uses the global type registry to resolve the message type and
// construct a new instance of that message to unmarshal into. In order for a
// message type to appear in the global registry, the Go type representing that
// protobuf message type must be linked into the Go binary. For messages
// generated by protoc-gen-go, this is achieved through an import of the
// generated Go package representing a .proto file.
//
// A common pattern with UnmarshalNew is to use a type switch with the resulting
// proto.Message value:
//
// switch m := m.(type) {
// case *foopb.MyMessage:
// ... // make use of m as a *foopb.MyMessage
// case *barpb.OtherMessage:
// ... // make use of m as a *barpb.OtherMessage
// case *bazpb.SomeMessage:
// ... // make use of m as a *bazpb.SomeMessage
// }
//
// This pattern ensures that the generated packages containing the message types
// listed in the case clauses are linked into the Go binary and therefore also
// registered in the global registry.
//
// # Type checking an Any
//
// In order to type check whether an Any message represents some other message,
// then use the MessageIs method:
//
// if any.MessageIs((*foopb.MyMessage)(nil)) {
// ... // make use of any, knowing that it contains a foopb.MyMessage
// }
//
// The MessageIs method can also be used with an allocated instance of the target
// message type if the intention is to unmarshal into it if the type matches:
//
// m := new(foopb.MyMessage)
// if any.MessageIs(m) {
// if err := any.UnmarshalTo(m); err != nil {
// ... // handle error
// }
// ... // make use of m
// }

// `Any` contains an arbitrary serialized protocol buffer message along with a
// URL that describes the type of the serialized message.
//
// Protobuf library provides support to pack/unpack Any values in the form
// of utility functions or additional generated methods of the Any type.
//
// Example 1: Pack and unpack a message in C++.
//
// Foo foo = ...;
// Any any;
// any.PackFrom(foo);
// ...
// if (any.UnpackTo(&foo)) {
// ...
// }
//
// Example 2: Pack and unpack a message in Java.
//
// Foo foo = ...;
// Any any = Any.pack(foo);
// ...
// if (any.is(Foo.class)) {
// foo = any.unpack(Foo.class);
// }
// // or ...
// if (any.isSameTypeAs(Foo.getDefaultInstance())) {
// foo = any.unpack(Foo.getDefaultInstance());
// }
//
// Example 3: Pack and unpack a message in Python.
//
// foo = Foo(...)
// any = Any()
// any.Pack(foo)
// ...
// if any.Is(Foo.DESCRIPTOR):
// any.Unpack(foo)
// ...
//
// Example 4: Pack and unpack a message in Go
//
// foo := &pb.Foo{...}
// any, err := anypb.New(foo)
// if err != nil {
// ...
// }
// ...
// foo := &pb.Foo{}
// if err := any.UnmarshalTo(foo); err != nil {
// ...
// }
//
// 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 {
state protoimpl.MessageState `protogen:"open.v1"`
// A URL/resource name that uniquely identifies the type of the serialized
// protocol buffer message. This string must contain at least
// one "/" character. 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).
//
// 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
// server that maps type URLs to message definitions as follows:
//
// - If no scheme is provided, `https` is assumed.
// - 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.)
//
// Note: this functionality is not currently available in the official
// protobuf release, and it is not used for type URLs beginning with
// type.googleapis.com. As of May 2023, there are no widely used type server
// implementations and no plans to implement one.
//
// Schemes other than `http`, `https` (or the empty scheme) might be
// used with implementation specific semantics.

//
// ╔════════════╤═════════════════════════════════════╗
// ║ Go type │ Protobuf kind ║

// Multiple protobuf Kinds may be represented by a single Go type if the type
// can losslessly represent the information for the proto kind. For example,
// [Int64Kind], [Sint64Kind], and [Sfixed64Kind] are all represented by int64,
// but use different integer encoding methods.
//
// The [List] or [Map] types are used if the field cardinality is repeated.
// A field is a [List] if [FieldDescriptor.IsList] reports true.
// A field is a [Map] if [FieldDescriptor.IsMap] reports true.
//
// Converting to/from a Value and a concrete Go value panics on type mismatch.
// For example, [ValueOf]("hello").Int() panics because this attempts to
// retrieve an int64 from a string.
//
// [List], [Map], and [Message] Values are called "composite" values.
//
// A composite Value may alias (reference) memory at some location,
// such that changes to the Value updates the that location.
// A composite value acquired with a Mutable method, such as [Message.Mutable],
// always references the source object.
//
// For example:
//
// // Append a 0 to a "repeated int32" field.
// // Since the Value returned by Mutable is guaranteed to alias
// // the source message, modifying the Value modifies the message.
// message.Mutable(fieldDesc).List().Append(protoreflect.ValueOfInt32(0))
//
// // Assign [0] to a "repeated int32" field by creating a new Value,
// // modifying it, and assigning it.
// list := message.NewField(fieldDesc).List()
// list.Append(protoreflect.ValueOfInt32(0))
// message.Set(fieldDesc, list)
// // ERROR: Since it is not defined whether Set aliases the source,
// // appending to the List here may or may not modify the message.
// list.Append(protoreflect.ValueOfInt32(0))
//
// Some operations, such as [Message.Get], may return an "empty, read-only"
// composite Value. Modifying an empty, read-only value panics.
type Value value
// The protoreflect API uses a custom Value union type instead of any
// to keep the future open for performance optimizations. Using an any
// always incurs an allocation for primitives (e.g., int64) since it needs to
// be boxed on the heap (as interfaces can only contain pointers natively).
// Instead, we represent the Value union as a flat struct that internally keeps
// track of which type is set. Using unsafe, the Value union can be reduced
// down to 24B, which is identical in size to a slice.
//
// The latest compiler (Go1.11) currently suffers from some limitations:
// • With inlining, the compiler should be able to statically prove that
// only one of these switch cases are taken and inline one specific case.
// See https://golang.org/issue/22310.

All rights reserved.
// Use of this source code is governed by a BSD-style
// license that can be found in the LICENSE file.
// Package protoreflect provides interfaces to dynamically manipulate messages.
//
// This package includes type descriptors which describe the structure of types
// defined in proto source files and value interfaces which provide the
// ability to examine and manipulate the contents of messages.
//
// # Protocol Buffer Descriptors
//
// Protobuf descriptors (e.g., [EnumDescriptor] or [MessageDescriptor])
// are immutable objects that represent protobuf type information.
// They are wrappers around the messages declared in descriptor.proto.
// Protobuf descriptors alone lack any information regarding Go types.
//
// Enums and messages generated by this module implement [Enum] and [ProtoMessage],
// where the Descriptor and ProtoReflect.Descriptor accessors respectively
// return the protobuf descriptor for the values.
//
// The protobuf descriptor interfaces are not meant to be implemented by
// user code since they might need to be extended in the future to support
// additions to the protobuf language.
// The [google.golang.org/protobuf/reflect/protodesc] package converts between
// google.protobuf.DescriptorProto messages and protobuf descriptors.
//
// # Go Type Descriptors
//
// A type descriptor (e.g., [EnumType] or [MessageType]) is a constructor for
// a concrete Go type that represents the associated protobuf descriptor.
// There is commonly a one-to-one relationship between protobuf descriptors and
// Go type descriptors, but it can potentially be a one-to-many relationship.
//
// Enums and messages generated by this module implement [Enum] and [ProtoMessage],
// where the Type and ProtoReflect.Type accessors respectively
// return the protobuf descriptor for the values.
//
// The [google.golang.org/protobuf/types/dynamicpb] package can be used to
// create Go type descriptors from protobuf descriptors.
//
// # Value Interfaces
//
// The [Enum] and [Message] interfaces provide a reflective view over an
// enum or message instance. For enums, it provides the ability to retrieve
// the enum value number for any concrete enum type. For messages, it provides
// the ability to access or manipulate fields of the message.
//
// To convert a [google.golang.org/protobuf/proto.Message] to a [protoreflect.Message], use the
// former's ProtoReflect method. Since the ProtoReflect method is new to the
// v2 message interface, it may not be present on older message implementations.
// The [github.com/golang/protobuf/proto.MessageReflect] function can be used
// to obtain a reflective view on older messages.
//
// # Relationships
//
// The following diagrams demonstrate the relationships between
// various types declared in this package.
//

//
// • An [EnumType] describes a concrete Go enum type.
// It has an EnumDescriptor and can construct an Enum instance.
//
// • An [EnumDescriptor] describes an abstract protobuf enum type.
//
// • An [Enum] is a concrete enum instance. Generated enums implement Enum.

//
// • A [MessageType] describes a concrete Go message type.
// It has a [MessageDescriptor] and can construct a [Message] instance.
// Just as how Go's [reflect.Type] is a reflective description of a Go type,
// a [MessageType] is a reflective description of a Go type for a protobuf message.
//
// • A [MessageDescriptor] describes an abstract protobuf message type.
// It has no understanding of Go types. In order to construct a [MessageType]
// from just a [MessageDescriptor], you can consider looking up the message type
// in the global registry using the FindMessageByName method on
// [google.golang.org/protobuf/reflect/protoregistry.GlobalTypes]
// or constructing a dynamic [MessageType] using
// [google.golang.org/protobuf/types/dynamicpb.NewMessageType].
//
// • A [Message] is a reflective view over a concrete message instance.
// Generated messages implement [ProtoMessage], which can convert to a [Message].
// Just as how Go's [reflect.Value] is a reflective view over a Go value,
// a [Message] is a reflective view over a concrete protobuf message instance.
// Using Go reflection as an analogy, the [ProtoMessage.ProtoReflect] method is similar to
// calling [reflect.ValueOf], and the [Message.Interface] method is similar to
// calling [reflect.Value.Interface].

// • An [ExtensionType] describes a concrete Go implementation of an extension.
// It has an [ExtensionTypeDescriptor] and can convert to/from

// • An [ExtensionTypeDescriptor] is an [ExtensionDescriptor]
// which also has an [ExtensionType].
//
// • An [ExtensionDescriptor] describes an abstract protobuf extension field and
