    # The canonical error codes for gRPC APIs.

    #
    # Sometimes multiple error codes may apply.  Services should return
    # the most specific error code that applies.  For example, prefer

    # Similarly prefer `NOT_FOUND` or `ALREADY_EXISTS` over `FAILED_PRECONDITION`.

      # The client specified an invalid argument.  Note that this differs

      # The deadline expired before the operation could complete. For operations
      # that change the state of the system, this error may be returned

      # used if the caller can not be identified (use `UNAUTHENTICATED`
      # instead for those errors). This error code does not imply the

      # to be deleted is non-empty, an rmdir operation is applied to
      # a non-directory, etc.
      #
      # Service implementors can use the following guidelines to decide
      # between `FAILED_PRECONDITION`, `ABORTED`, and `UNAVAILABLE`:
      #  (a) Use `UNAVAILABLE` if the client can retry just the failing call.
      #  (b) Use `ABORTED` if the client should retry at a higher level
      #      (e.g., when a client-specified test-and-set fails, indicating the
      #      client should restart a read-modify-write sequence).
      #  (c) Use `FAILED_PRECONDITION` if the client should not retry until
      #      the system state has been explicitly fixed.  E.g., if an "rmdir"
      #      fails because the directory is non-empty, `FAILED_PRECONDITION`
      #      should be returned since the client should not retry unless
      #      the files are deleted from the directory.

      # reading past end-of-file.
      #
      # Unlike `INVALID_ARGUMENT`, this error indicates a problem that may
      # be fixed if the system state changes. For example, a 32-bit file
      # system will generate `INVALID_ARGUMENT` if asked to read at an
      # offset that is not in the range [0,2^32-1], but it will generate
      # `OUT_OF_RANGE` if asked to read from an offset past the current
      # file size.
      #
      # There is a fair bit of overlap between `FAILED_PRECONDITION` and
      # `OUT_OF_RANGE`.  We recommend using `OUT_OF_RANGE` (the more specific
      # error) when it applies so that callers who are iterating through
      # a space can easily look for an `OUT_OF_RANGE` error to detect when
      # they are done.
