-//
-// This header file defines the Abseil `status` library, consisting of:
-//
-//   * An `absl::Status` class for holding error handling information
-//   * A set of canonical `absl::StatusCode` error codes, and associated
-//     utilities for generating and propagating status codes.
-//   * A set of helper functions for creating status codes and checking their
-//     values
-//
-// Within Google, `absl::Status` is the primary mechanism for gracefully
-// handling errors across API boundaries (and in particular across RPC
-// boundaries). Some of these errors may be recoverable, but others may not.
-// Most functions that can produce a recoverable error should be designed to
-// return an `absl::Status` (or `absl::StatusOr`).
-//
-// Example:
-//
-// absl::Status myFunction(absl::string_view fname, ...) {
-//   ...
-//   // encounter error
-//   if (error condition) {
-//     return absl::InvalidArgumentError("bad mode");
-//   }
-//   // else, return OK
-//   return absl::OkStatus();
-// }
-//
-// An `absl::Status` is designed to either return "OK" or one of a number of
-// different error codes, corresponding to typical error conditions.
-// In almost all cases, when using `absl::Status` you should use the canonical
-// error codes (of type `absl::StatusCode`) enumerated in this header file.
-// These canonical codes are understood across the codebase and will be
-// accepted across all API and RPC boundaries.

-// absl::StatusCode
-//
-// An `absl::StatusCode` is an enumerated type indicating either no error ("OK")
-// or an error condition. In most cases, an `absl::Status` indicates a
-// recoverable error, and the purpose of signalling an error is to indicate what
-// action to take in response to that error. These error codes map to the proto
-// RPC error codes indicated in https://cloud.google.com/apis/design/errors.
-//
-// The errors listed below are the canonical errors associated with
-// `absl::Status` and are used throughout the codebase. As a result, these
-// error codes are somewhat generic.
-//
-// In general, try to return the most specific error that applies if more than
-// one error may pertain. For example, prefer `kOutOfRange` over
-// `kFailedPrecondition` if both codes apply. Similarly prefer `kNotFound` or
-// `kAlreadyExists` over `kFailedPrecondition`.
-//
-// Because these errors may travel RPC boundaries, these codes are tied to the
-// `google.rpc.Code` definitions within
-// https://github.com/googleapis/googleapis/blob/master/google/rpc/code.proto
-// The string value of these RPC codes is denoted within each enum below.
-//
-// If your error handling code requires more context, you can attach payloads
-// to your status. See `absl::Status::SetPayload()` and
-// `absl::Status::GetPayload()` below.
-enum class StatusCode : int {
-  // StatusCode::kOk
-  //
-  // kOK (gRPC code "OK") does not indicate an error; this value is returned on
-  // success. It is typical to check for this value before proceeding on any
-  // given call across an API or RPC boundary. To check this value, use the
-  // `absl::Status::ok()` member function rather than inspecting the raw code.

-  // typically by the caller.

-
-  // StatusCode::kUnknown
-  //
-  // kUnknown (gRPC code "UNKNOWN") indicates an unknown error occurred. In
-  // general, more specific errors should be raised, if possible. Errors raised
-  // by APIs that do not return enough error information may be converted to
-  // this error.
-  kUnknown = 2,
-
-  // StatusCode::kInvalidArgument
-  //
-  // kInvalidArgument (gRPC code "INVALID_ARGUMENT") indicates the caller
-  // specified an invalid argument, such a malformed filename. Note that such
-  // errors should be narrowly limited to indicate to the invalid nature of the
-  // arguments themselves. Errors with validly formed arguments that may cause
-  // errors with the state of the receiving system should be denoted with
-  // `kFailedPrecondition` instead.
-  kInvalidArgument = 3,
-
-  // StatusCode::kDeadlineExceeded
-  //
-  // kDeadlineExceeded (gRPC code "DEADLINE_EXCEEDED") indicates a deadline

-// absl::Status
-//
-// The `absl::Status` class is generally used to gracefully handle errors
-// across API boundaries (and in particular across RPC boundaries). Some of
-// these errors may be recoverable, but others may not. Most
-// functions which can produce a recoverable error should be designed to return
-// either an `absl::Status` (or the similar `absl::StatusOr<T>`, which holds
-// either an object of type `T` or an error).
-//
-// API developers should construct their functions to return `absl::OkStatus()`
-// upon success, or an `absl::StatusCode` upon another type of error (e.g
-// an `absl::StatusCode::kInvalidArgument` error). The API provides convenience
-// functions to constuct each status code.
-//
-// Example:
-//
-// absl::Status myFunction(absl::string_view fname, ...) {
-//   ...
-//   // encounter error
-//   if (error condition) {
-//     // Construct an absl::StatusCode::kInvalidArgument error
-//     return absl::InvalidArgumentError("bad mode");
-//   }
-//   // else, return OK
-//   return absl::OkStatus();
-// }
-//
-// Users handling status error codes should prefer checking for an OK status
-// using the `ok()` member function. Handling multiple error codes may justify
-// use of switch statement, but only check for error codes you know how to
-// handle; do not try to exhaustively match against all canonical error codes.
-// Errors that cannot be handled should be logged and/or propagated for higher
-// levels to deal with. If you do use a switch statement, make sure that you
-// also provide a `default:` switch case, so that code does not break as other
-// canonical codes are added to the API.
-//
-// Example:
-//
-//   absl::Status result = DoSomething();
-//   if (!result.ok()) {
-//     LOG(ERROR) << result;
-//   }
-//
-//   // Provide a default if switching on multiple error codes
-//   switch (result.code()) {
-//     // The user hasn't authenticated. Ask them to reauth
-//     case absl::StatusCode::kUnauthenticated:
-//       DoReAuth();
-//       break;
-//     // The user does not have permission. Log an error.
-//     case absl::StatusCode::kPermissionDenied:
-//       LOG(ERROR) << result;
-//       break;
-//     // Propagate the error otherwise.
-//     default:
-//       return true;
-//   }
-//
-// An `absl::Status` can optionally include a payload with more information
-// about the error. Typically, this payload serves one of several purposes:
-//
-//   * It may provide more fine-grained semantic information about the error to
-//     facilitate actionable remedies.
-//   * It may provide human-readable contexual information that is more
-//     appropriate to display to an end user.
-//
-// Example:
-//
-//   absl::Status result = DoSomething();
-//   // Inform user to retry after 30 seconds
-//   // See more error details in googleapis/google/rpc/error_details.proto
-//   if (absl::IsResourceExhausted(result)) {
-//     google::rpc::RetryInfo info;
-//     info.retry_delay().seconds() = 30;
-//     // Payloads require a unique key (a URL to ensure no collisions with
-//     // other payloads), and an `absl::Cord` to hold the encoded data.
-//     absl::string_view url = "type.googleapis.com/google.rpc.RetryInfo";
-//     result.SetPayload(url, info.SerializeAsCord());
-//     return result;

-// absl::StatusOr<T>
-//
-// The `absl::StatusOr<T>` class template is a union of an `absl::Status` object
-// and an object of type `T`. The `absl::StatusOr<T>` models an object that is
-// either a usable object, or an error (of type `absl::Status`) explaining why
-// such an object is not present. An `absl::StatusOr<T>` is typically the return
-// value of a function which may fail.
-//
-// An `absl::StatusOr<T>` can never hold an "OK" status (an
-// `absl::StatusCode::kOk` value); instead, the presence of an object of type
-// `T` indicates success. Instead of checking for a `kOk` value, use the
-// `absl::StatusOr<T>::ok()` member function. (It is for this reason, and code
-// readability, that using the `ok()` function is preferred for `absl::Status`
-// as well.)
-//
-// Example:
-//
-//   StatusOr<Foo> result = DoBigCalculationThatCouldFail();
-//   if (result.ok()) {
-//     result->DoSomethingCool();
-//   } else {
-//     LOG(ERROR) << result.status();
-//   }
-//
-// Accessing the object held by an `absl::StatusOr<T>` should be performed via
-// `operator*` or `operator->`, after a call to `ok()` confirms that the
-// `absl::StatusOr<T>` holds an object of type `T`:
-//
-// Example:
-//
-//   absl::StatusOr<int> i = GetCount();
-//   if (i.ok()) {
-//     updated_total += *i
-//   }
-//
-// NOTE: using `absl::StatusOr<T>::value()` when no valid value is present will
-// throw an exception if exceptions are enabled or terminate the process when
-// execeptions are not enabled.
-//
-// Example:
-//
-//   StatusOr<Foo> result = DoBigCalculationThatCouldFail();
-//   const Foo& foo = result.value();    // Crash/exception if no value present
-//   foo.DoSomethingCool();
-//
-// A `absl::StatusOr<T*>` can be constructed from a null pointer like any other
-// pointer value, and the result will be that `ok()` returns `true` and
-// `value()` returns `nullptr`. Checking the value of pointer in an
-// `absl::StatusOr<T>` generally requires a bit more care, to ensure both that a
-// value is present and that value is not null:
-//
-//  StatusOr<std::unique_ptr<Foo>> result = FooFactory::MakeNewFoo(arg);
-//  if (!result.ok()) {
-//    LOG(ERROR) << result.status();
-//  } else if (*result == nullptr) {
-//    LOG(ERROR) << "Unexpected null pointer";
-//  } else {
-//    (*result)->DoSomethingCool();
-//  }
-//
-// Example factory implementation returning StatusOr<T>:
-//
-//  StatusOr<Foo> FooFactory::MakeFoo(int arg) {
-//    if (arg <= 0) {
-//      return absl::Status(absl::StatusCode::kInvalidArgument,
-//                          "Arg must be positive");
-//    }
-//    return Foo(arg);
